Well puling the loom from the coils made it run a bit rougher on each one, so that rules the out. Unplugging the afm made the car stall, so it must be working to some degree.

How big an effect will an leak in cooler piping have at idle?

Got this same problem I've been battling for a couple of weeks.

Changed pump Changed plugs gapped to .8 . Checked piping. Problem went away basically after the Pump Then one day the misfire returned worse than ever was almost constant I changed the fuel filter and had a mild improvement

. Pulled the pump out and the sock was so jammed with dirt it wasn't pulling through. Cleaned it out and all good again . Has started to come back again after a week. Anyway i reckon pull your pump out as the sick is probably full of shit

My car did the same thing the day after i got it (blew the intercooler pipe off) Was told it was a realy small hole but F#*K me, it ran like it was on 3 cylinders and blew alot of black smoke. Even if you can't find any obviouse leaks in the intercooler pipeing just have a realy close and good leak. Apart from that i would just do what everyone else is suggesting. Hope you get her running 100% soon :)

alot.

my AFM was rooted, but it still stalled when you unplugged it.

edit: are you north or south?

Im down south Dion. my car is currently taking up space in my gfs parents garage in Morphett Vale :P

a mate had similar issues, new spark plugs, tested different AFM and bought new coilpacks and in the end it turned out to be the ignition module...

Cheers Vu, will add that to the list

okies, will do. what did you use to clean up the pump, im guessing there are some solvents/cleaning products to steer clear of in case they react with petrol

hmm wouldnt have thought a small leak would have such a large effect, we'll see!

Hey Carl

I'm putting my money on boost leak bud

Rough idle , hunting, blowing smoke......all symptoms of an intercooler pipe pissing out somewhere

looks like its the next step

If it's IC piping, you owe me a blowie.

Borrow a working AFM from someone to rule that out too and save you the head f**k of buying one if it's not the problem.

fark that is a fairly steep price for IC piping being the cause :P

Yeah if your silicone joiners are a bit old, thats probably the cheapest way to start!

yeop, my thoughts as well... i have done everything that is free so far. time to move on to the cheap fixes :D

finally got some more time to mess about with the car. replaced a bunch of the joiners with fresh look at me blue silicon and new clamps. there were a couple sections that i could not find replacments for (they have a gradual curve in them) so i have not completely ruled out a vacuum leak.

a couple things that i have noticed in the way that it is running are:

  • it runs slightly smoother at idle. however it is still blowing a ton of smoke at idle and makes a nice cloud on gear changes and acceleration in 1st
  • after a bit if driving then coming to a stop it idles at 2k rpm for a little while (up to 1 min) then it drops back down to around 1k rpm and will surge/splutter.
  • when driving at a steady rpm, a change in throttle position makes the car surge/splutter
  • does not blow smoke driving at a steady speed
  • does not want to boost past 8psi (not that i have been trying to, but the slippery clutch means sometimes i dont have much choice in gointg to higher rpm)

does that info help narrow it down for all?

anyone out there have a working green sticker AFM or RB20 igniter pack i can try out this coming weekend? i work in the city and live in the brighton area

ps, thanks for the help so far :cheers:

Igniter pack will be solid gold bro!

Will clean out my aac this weekend, can hopefully sort an afm to test as well.

Faililng those telling me what the problem is it leaves a vacuum leak that is still there, a borked CAS. Or something more sinister

You my friend are in luck......i have a spare igniter pack and creank angle sensor you can try, but i'm not sure how well the sensor will work as it hit the ground when i pulled it of my spare motor. If you want i can drop them off on my way home from tafe tomorrow arvo (finish at 4:50) so just txt or PM me the addy.

    • 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.
