:D Hi guys I have been having on going problems with my r33. See thread http://www.skylinesaustralia.com/forums/in...howtopic=148411

I tried to book into a work shop but they are all closed till hte 15th of this month, i cant wait this long as this is my only car and it is becoming undrivalbe and i dont want to risk causeing any damage.

I am willing to offer money to some one who can help me fix my car.

If any one has time this weekend or sooner can you please pm, it would be greatly appreciated.

I am willing ot negotiate paymment for labour either a hourly rate for some set charge.

I know there has to be some knowledgeable guys on here.

How much are you willing to do yourself? There are a few things you can try that might help your problem.

By the sounds of your other thread though the car is running hugely rich, which would explain the problems you're having, so I'd be checking things that will alter the amount of fuel being pumped in. I'm definitely not a mechanic but check these things in no particular order:

1) Clean the AFM with electrical contact cleaner

2) Change the fuel filter

3) Check the output from the throttle position sensor, you can of course do this with the ignition on and the motor off, so you don't have to rev the crap out of it. You're basically after a smooth linear voltage increase. I think the standard range is 0.65V (closed throttle) through to 4.8V (full throttle), but look it up because I'm going from memory and am probably wrong lol

4) It shouldn't make a difference but swap to another known good fuel pump

5) Swap ECUs with someone else, keeping in mind that S1 ECUs are different to S2. If you have an ignitor box (bolted to the top of the engine, right up the back near the firewall, behind the stock BOV) then you need a S1 ECU.

I haven't listed things like sticking injectors because you've said the carbon buildup is consistent across all 6 cyls.

Failing this, if you'd still like someone to have a look at it, you could try contacting Dan (send a PM to 3lit3 32 on these forums), he knows his Skylines and has helped out quite a few members of this board. I'm not sure whether he's having time off over the break but it never hurts to check :D

thanks for the info RevHead,

I tried cleaning both the airflow meteres, i even resoldered one of them just to be sure.

I am leaning towards what ur thinking but i am unsure how to set the TPS, will i just need a volt/amp meter?

Oh and i changed the fuel filter that was the first thing i did when the problems started.

i should just note that a s1 ecu can be used in a s2. they are the same. people seem to think that s2's have the ignitor built into the ecu, but it is in the coil packs, not the ecu.

i am currently running a s1 ecu with a s2 motor.

I thought thas was the case but wasnt sure.

does any on ein bris have a ecu i might be able to swap out and try for a small fee?

Another thought, if i had a air leak some where would htis make the car hesitate servely under load?

I have checked all IC piping and no leaks but what about the plenum runneres etc?

i'd check you crank angle sensor. i was working on a mates 180sx a few weeks back, and the CAS was slightly shagged. it was as slow as a wet week. you put your foot down and it was like driving with your foot hard on the brake.

try doing this as a test. advance your timing as far as it will go then go for a spin. this may make it ping its arse off, so only drive down the road and back. if you do this and the car runs fine then i'd say it is your crank angle sensor. and if you do it and there is no sound of pinging then you should be able to leave it like that until you can get a new one.

is there anyway of testing afaulty crank angle sensor??

I think u can test the cas with a volt meter some how. I simply unplugged it and tried to start the car and it would not start at all. Pluged it back in and it started fine.

I initially was thinking faulty CAS but after reading up how htey work and fail i doubt that is my problem.

When the cas goes it just dies and ur can run any more i don tbelieve it gets dodgy and has symptoms before it dies.

Worth a try tho.

any other suggestions?

the easy way to test it is to try someone elses. other than that i'm not sure.

when you change them over you have to make sure that the new one is lined up. they have a half moon type thing in the end of them.

Does any one know of the syptoms of a gying cas? or experienced any cas related problems?

a bit confusing your reply but (typing mainly).rb's run similar set up as CA18det' engines as far as cas go ( i read up a story on them in one of the import mags and sounds similar to your prob) when it come to cas,now if the cas is faulty it will scatter timing when the spline gets flogged out causing confusion for the computer. to what i believe to which it sounds like thats what is happening,can you go a wrecker and get on and try it at least? is it worse when you run more boost??

with my mates 180sx, when we retarded the timing we got to a point (about 1/3 of the way back from full advance) where the car would just start running like complete crap. anywhere above that and it ran ok, but below that it ran like crap. we had originally thought that the water temp sender may have been dead and making the engine think it was really really cold and retarding the timing heaps and dumping fuel in, but it seemed fine. we tested it, and swapped it with another one and nothing changed. that may be worth testing also.

yeah thats the one,he should try that then if that doesnt work throw a match down the fuel filler and run.lol

Lmao well before i go out and buy a box of matches hahah

Im pretty sure my cas is intact but i will re check the locator. I will also get my timming checked again to make sure its a 15 base.

The car really runs slow to the point its hard to accelerate wiht traffic, over taking faster than an excell is way too optimistic.

i dont want to spend the money buying a cas and finding out that didnt fix it. Does any one have one i can try?

If the locator is fine and nothing seems broken , then coud the sensor still be failty?

Thanks guys

i kept telling my mate that the problem was that it was a ca18 and no matter what we did to the motor it wasn't going to be fast.

his problem originally started only when the car was cold, and when it warmed up it would go away. then it started doing it all the time.

um no i dont have one really that i could lend you but you can just go buy one make sure it has a warranty then if you swap it over and the prob is still there just take it back and say its faulty.im not 100% sure if they can be electroncally tested maybe someone on here knows.but yeah good suggestion is to advance it first and see how you go.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
