maf

[broncoupe]

hi all i have sa euro m3 evo, i get a iregular miss at idle and feel the car is down on power, it just feels off. i have checked everything even put it on winstar, no stored faults tps .6 - 4.1 what i am now thinking is maf disconnecting it throughs a stored fault but it substitutes a value to keep the engine running.air temp, oil temp,water temp all seem about right, what are maf symptoms? thanks all

irregular idle, running rich, down on power, but it will always trip a check engine light and store a code. Have you checked your catalysts lately? these can create a situation like you are describing. Also, poor fuel quality or fuel filter will do the same.

there are any number of things that it could be.

do you have a meter that you can tell take readings off the MAF>
