Ok here is the story - My car started idling like shit and I started to get a check engine light. I took it to the local Toyota Dealership. They ran their diagnostic test and told me that my MAF sensor was bad. I decided to buy the Lexus AFM, and now that it is on my car is still throwing the check engine light and my car is still idling rough. I was told that it may take a while for the ECU to read the new AFM. Is this true? I took off my negative battery cable today to help fix it. Nothing changed. Was I supposed to do something else after replacing the AFM like waiting a specific amount of time before starting my car back up or what? Am unsure of what to do from here and am tired of having a car that runs like ass. Am waiting on my 550's in case you were wondering. PLEASE POST YOUR THOUGHTS. Thanks.

check your codes.

Ditto on checkin the codes. The Toyota shop may have said bad MAF but it might be a broken wire if you switched units and both are causing a $h!tty running sup.

what kind of a broken wire. i'm not too smart about the technical side to a supra, not even sure if i could check this kinda stuff out myself. can anyone give me any tips or instructions.

If you can't do this type of stuff, then just take it to another dealer, or ask around and take it to a shop that knows Supras.

so its not my AFM. the dealership told me that the sensor was bad and that is what the code was reading. so it doesn't take time for the ECU to read the new AFM? thats not the problem?

 

[Guest]

ok, ran the codes. It threw out 4 diff. codes on me. Any ideas?

 

[Guest]

Because we can help you without you telling us which codes they were...

24 - Intake Air Temp Sensor Signal
31 - Air Flow Meter Signal
42 - Vehicle Speed Sensor Signal
51 - NO CLUE

i think 51 is TPS (throttle position sensor)

so which one do you think is causing this bad idle? are any of you on AIM or MSN or Yahoo so I can chat with ya about this rather than post it?
