Default Subaru Erratic Idleing

I have done a reverse inlet, stainless headers, light weight flywheel, light crank pulley, apexi boost control kit. I have done all of these mods all in one hit but its running ok but seems to have an Erratic Idle and a slight misfire. Just wondered if anyone had an ideas what could be causing it.

Have you had it mapped? If not, that's your problem.

Could be a leak around the inlet manifold, vac pipes, IC pipework.... Also check the timing, mine had an erratic idle when one of the exhaust cams was a tooth out.

Mine also had the idle problem... Would sit at 1500rpm... Then sometimes would just Rev up to 2500rpm, then drop, then up again....

Since My Re-Map @ Andy Forrest on Monday, it`s all cured.... No Rev, Idle Issues At All Now

Default Thanks for the replies

Hi FurballPhil I have got exactly the same as you discribed so hoping that once its mapped it might be ok. I have got Simon coming round Tuesday so im sure he will be able to sort it out for me.
Thanks again

Yep, My Car had never been a good idler since I got her over a year ago.
But now, since Monday`s Mapping she sits purring away nicely... So, I`m sure Simon will cure it.. Or at least find the root of the problem if it`s something else

ECU check with the connectors under the dash board.

er.............I think you need it mapped. How can you expect it to idle properly after everything you have done without mapping it?
