Suggestions On What Is Wrong?

cry41t,

What boost are you running? Chances are its hitting R&R.

Nah, doesnt matter if im running 8,10,12 psi still a flat spot within a certain rev range.

Previously it was spiratical and the coil packs fixed that, but a couple of mechanics are attributing the flat spot to the standard fuel pump, due to all my upgrades.

Need a pump either way, but am expecting it to cure the flat spot.

well it fixed my missfiring i suppose but although the thing had some balls for a week or 2 its gone again now. I drove it to torquay (2 hour drive) messed around up there, came back, parked the car for a day, and next time i got in it noticed it sucked again, It just flats out from 3krpm-6.2krpm, no extra pull. When it was "fixed" it used to kick in as much till about 4krpm then really push u bak so..

Ive done all i can think to do on it. Dunno where to try fix next

Make sure u replace filter when u do pump and run some injector cleaner thru (might wana replace the hoses for filter to), then youll get that section out of the question easily enough

Happy as...........

Had the pump installed yesterday and now the thing is going like a rocket and boosting smoothly.

Pity it couldnt have been the same situation for you (r32 gts turbo)

heheh well it did fix it for a week of bliss but oh well back to dodgyness, need the stupid thing fixd, im sick of ppl getting in it and going "this is almost as fast as my dads vy executive" -_-

You really should have your coil packs tested.

Sometimes hairline fractures can occur and cant be seen and most mechanics should have the facilities to test them.

Hmm ive looked at the cases on all of them, done voltage test on all of them and checked all the contacts, so im thinking they shouldnt be my prob. Im gonna try find a guide somewhere on injectors, and rip them out, post some pics up here to see if there all cool, thx

Edit - Getting fuel pressure/flow test done tonight, see what happens

to check the coils, unbolt them from the bracket, and lift them up by the wiring whilst the motor is running you can here and see the sparks coming out the side off the coil ive seen 4 dead coils on cars that drive fine until you boot it
