Hi guys, have been having an issue with hesitation or missing.
At first it only happened when the car came on boost hard, it would hesitate badly, not smooth boost delivery, choppy. But this does not happen all the time, sometimes it is fine when it is on boost.
Lately it feels like it is hesitating/missing more just when driving around normally, ie: off boost under a bit of throttle. Again, this does not occur all the time either. Sometimes on idle it feels rough and sounds like its missing, other times it idles fine.
Yesterday, when I started it up it sounded like a WRX for a few minutes, then it went back to sounding normal.
Cant be air flow metres as I run a Vipec which doesnt need them. I have the usual bolt on upgrades; -5s, bigger injectors, fuel rail, fuel pump, cam gears, zorst, etc.
Car had been running like a dream since tune, this problem has just started up in last couple of weeks or so.
Coilpacks are still the stockies, do you rekon this is my problem? Are coilpack issues limited to off boost or on boost or can it be both as per what is happening with my car??
Or what else do you think could be causing my issues?
Thanks people
