R32 Gts-t Problems

[Malteaz]

Hi

If anyone can shed some light on the below and give me some advice, that would be grand!

So, i've had it for 5 or so months & it's a 93 R32 gts-t running 12psi

Mods:

Fmic

3in exhaust

bov

pod

Recently had 100k service done, spark plugs changed, & new piping on the intercooler as the old ones were cracked, leaking air & giving no boost.

Car has stock ecu & is yet to be tuned.

My troubles:

1.When either in boost or not(generally not), power will cut up to a second, then re engage. Mostly when the car is a little colder, but does do it when warm.

2. If i go to change gears, but don't & just let it hang in nuetral, instead of dropping back to just under 1grand it will either stall, or stutter and then even out.

3. Recently a few times when stationary car has rev'd itself then hit 0 and either regained and trys again or stalls

Rev's ocasionally seem to sit above 1grand then eventually evens out and rests at just under.

Cant say my knowledge on cars is very high so please excuse my noobness.

Possibly due to it needing a tune?

Thanks for your help!

Replace it with the stock bypass valve.

Sounds like too much fuel going in and killing it. Could be a leak, need a tune, bad fuel reg, atmo box, or something I have missed...

2lv - do u mean bov leak?

Yeah i could be looking at getting a new afm - my mechanic says not much point in cleaning the afm as it will chew away at the plastic on the rod or something like that. Any truth in that comment?

Use some electrical contact cleaner, will be fine. Just remember he is a mechanic not an auto elec
