Default still MAF (i think) problems.. car randomly lets off while accelerating in all gears and occasionall

y dies @ idle. My exhaust is pretty coated in black grit so that makes me think i'm running rich.. after car dies at idle its often very hard to start.. i normally have to let it sit for a few minutes. engine flooded? I've taken my airbox off and everything looks clean where the MAF connects to the box.. does this sound in fact like its a faulty MAF....? Thanksss

Default Have you ran codes on the car?

If you don't have a VAG-COM, or know anyone who does, at least go to Autozone and pull the codes. Otherwise it's just guesswork.

1.) There is no "CPU" on the car; 2. Those aren't SAE codes.

Default well the cars port under the left of the steering wheel.. as for the codes not being SAE.. ****

just checked.. while at idle if i put the AC on after a few moments the rpms drop drastically and the car almost dies and then it catches goin again.. so am i basically screwed if i can't get the codes.. i live up in the (santa cruz) mountains in cali and am afraid if i take my car down to an autozone i wont be able to get it back up the hill..

Try using electrical cleaner, spray some on the MAF sensor, that should help.

Default the 2 bars on the inside of the sensor? i undid my airbox and peaked in there and it looked cleannn

where the maf connects to the airbox.. i could see the 2 wires inside and the grate and all looked clean.. would i see anything or is it invisible to the eye? would i literally spray the inside?

Default Yes, literally spray the inside, it won't hurt anything. And you won't

be able to see if it's dirty, typically a thin oily film will cover the sensor which can cause it to operate incorectly. Most people don't need to replace their MAF's, it just depends on how bad it is. Also, alot of people will replace their MAF's for peace of mind since it is a common thing to go bad.

lol, it's called either the ECU or ECM. A good investment for any audi DIY'er is VAGCOM btw
