nice work, what are u getting done?

hey guys i was wondering if any one can solve this...

My cars been misfiring abit and it got to the stage where when i gave it up... it wouldn't rev over 5g it just bounces back and sounded like something was holding it back, and also sounded gross... i changed the spark plugs and coilpacks, and its still doing it.

It also misfires and backfires around 2g when im in a high gear at low revs... then when i was testing it last night showing a mechanic mate of mine it still wouldn't go over 4-5g it just shat itself and wouldn't let me rev high....

Is this my timing from the computer? does it need a tune up or is there something else im not aware of.

cheers

and another thing, does anyone one know is the r33 rb25 uses the same water pump as the rb25 in a r32?

Hey mate, I had similar missfires going on with my gtr aswell. Basically on a cold morning at times it wouldnt let me rev over 2.5g, I put in new coil packs and plugs and it seemed like it got better but then was doing it again after about a week.

Ended up putting it in and getting a new ECU and a dyno tune. Problem solved

I cant say whether it was just needing a tune or it had something to do with the ECU but once they were done its now running perfect.

also check that the wires pluging in to your afm are in tight and theres no water around there. i washed my motor down and i bumped the plug and some water got in there and i had exactly the same problem. i hope that helps.

I have had this problem befor as well and I had two problems on different occations. Fist time I have blown a pipe half off on the intake. The other time I had shorted A wire out near the battery. Both times the car juat ran really rich.

On another note i have my car back on the road after a couple of years of sitting in the shed WHOO BLOODY HOO!!

i changed the fuel filter today.. didnt help my situation at all.

When my cars cold it doesnt even rev over 2800 - 3000. it just jerks around... feels like a L plater driving, revs just bounce back... but when its hot it drives fine just backfires a wee bit around 2000 and then once i hit 5000 it does the jerking rev bouncing shit again.

AFM? Timing? Fuel reg/pressure reg?

changed anything recently?

checked for vac leaks?

checked the afm/and its connection?

tried resetting the ecu?

checked the plugs/spark.

got injection pulse? use a noid light to find this out.

check the bov, but more importantly the recirc hose.

all the clamps done up tight?

im no mechanic tho.

im sure chapmans would be able to 'fix' the issue for a small fee :happy::)

nice one dave. the gunmetal beast is back. didnt know u still had it.

mines for sale at the right price :happy:

daz i changed my coilpacks and sparkplugs, i checked out my AFM today, its all attached good... maybe the wiring is f**ked.

I also changed my fuel filter....

Martys ganna run it through his computer next week i think... hopfully it brings up the problem

also is there any dyno tuners on the coast?? or are they all in brissy?

cheers

Yeah I will never get rid of it, love the car too much.

Hey I am a bit out of the loop. Who is someone good to work on my car, I need a tune. Last time I went to anyone it was sub-zero on the goldy... That was a while ago...

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
