Here's my mods:
up pipe, down pipe, ported wastegate, apexi intake on an 04 sti
heres my problem:
irratic idoling from almost stalling to 2000 rpm, fuel cut at random rpm
It just started today when I started the car(first start today) it also gets speratic acceleration around 2000 rpm but not in every gear.
Any suggestions?thanx
josh

 

I'd say its the intake...try running stock intake and see wut happens....are u running an aftermarket BOV too??

 

no bov. why would the intake cause this kind of problem its pretty much just a filter

 

try resetting the ECU. unplug the terminal and hold ur foot on the brake. u need a 10 or 12mm socket for this i think.

start the car back up and see if the problems still there.

This is only common because the car's setting is not adapt to the modifications.

Something I have done is letting the car sit and idle for 10 minutes. The ECu will slowly learn idle.

I'd suggest Engine managment for optimum potential of your mods.
