Engine playing up.

[bad_gt]

Hey Guys Ive finally got my 94 wrx back on the road. Ive double checked everything before going for a test drive..I took it out for its first drive when suddenly it stalls but it doesn't turn off i hold my foot on the gas and out of nowhere it kicks back again. It really annoys me lol Ive got told it was a airflow meter, I changed that and still same problem. Just wanted to check if anyone went through this. Another odd thing is that it wont do this if i lean on the gas a bit. help please haha..

Car has current mods:

3inch turbo back.

Equal length extractors.

Trust Pod Filter.

Walbro 500hp fuel pump.

Full A/C delete.

sti injectors

Bov

Removed rocker cover breathers. Replaced with simota filters

Just listed mods just incase it affects the car.

have you changed the injectors and still using the original ecu and original colour AFM?

if so that'll be your problem, you cant just swap to different sized injectors

[bad_gt]

i figured that would've been the problem. I swapped the original ones back in and it made no difference. i even swapped ecu with my mates, still the same..

Checked the BoV to make sure it's not leaking on idle?

Fix this, your car is not speed-density, that is a vacuum leak, there's a reason they're plumbed back.

are you sure? I dont think its a vacuum leak as its on the wrong side of the pistons, its only letting blow by vent.

its not ideal as he'll end up with fuel/oil vapour everywhere but it shouldn't cause any drama unless he's done something funny with the PCV i.e left a hole in the intake without plugging it

Depends how healthy the PCV is and whether it has the secondary intake breather (before the throttle body/turbo straight from the block) If that is present it is a pretty big vacuum leak. Take your oil cap off and go for a drive if you want to see what I mean.

wont work on my car, I've got no PCV and just running a vented catch can

[bad_gt]

Got my car to work and hooked it up to a scanner, and yeah few codes got pulled up

52.Parking position switch

44.Turbocharging pressure control output signal

43.Accelerator pedal switch

33.Vehicle speed sensor

32.Oxygen sensor

24.Idle control system malfunction

15.Fuel injector #2

Haha oh well at least this gives me my answer( well hopefully:/)

What is code 44 though? is that got to do with the boost solenoid?
