Running lumpy
Hi everyone, i know you probably get this everyday but im new on here and after a bit of advice after hitting a brick wall trying to diagnose the issue,
I've got a 2003 Subaru Impreza 2.0 WRX and basically it is idling lumpy and running poor in low revs specially when the engine is cold.
At first i thought it was a misfire and changed the plugs but that hasn't resolved the issue.
The thing is, when i unplug the MAF is runs and idles fine.
Ive replaced the MAF twice now but still the same.
Ive replaced the air intake pipe incase there was a leak - but still the same
The thing that is boggling my head is that it runs fine without the MAF - Does that suggest its a air intake issue?
Thanks for your help guys
