Hi all, can anyone suggest what is wrong with my car? It's a 97 sti, when i i'm driving then come to a stop ( at lights etc) the engine revs start dipping and sounds like it's about to stall, but about 20-30 seconds later it settles down back to normal. Any suggestions?

 

hi i had bmw a few years back that used to do that, turns out there was a rip in the air flow hose (after) the air flow meter

could maybe be maf sensor or idle control valve as possible cuplprits mind

 

Hi check for air leaks ie any splits but i had similar problem and it was my MAF sensor but always look for the simplest problem first.

 

Ok will check those tomorrow. Could a dirty maf also cause this? cheers

 

possibly, i have a my99 which has the film type MAf rather than hot wire so im not too sure how you would go about cleaning it ,. but im prety sure u can
