Hey guys im proper annoyed to be honest i have recently just finished doing my car up :-)
but now when i drive it it started out as got to a certain rev and started chuggering and wouldnt go any faster, now its reving its self on 2rpm arghhhhh
droveit earlier and now its stil reving its self but its also chugging like a bitch and back fires :-/
told maybe maf sensor????

Help please

 

MAF sensor or sticking throttle control valve.

 

mine done exactly this few weeks ago , was idle control stuck open remove clean with brake cleaner and spray with bit of wd40, dont drive it like this as will be leaning out hence the misfire/backfire.

 

where abouts is the idle control?

 

What model/age car?
