yes MAF is the mass airflow sensor, and theres no fuse for it

since your service engine soon light is on please follow this procedure and report back to us with the codes: http://www.bonnevilleclub.com/forum/...e=article&k=57

the repairman took 676 USD just to do a test but he did not understand the what the problem was

please answer what i can do by myself
676 USD????? WTF!!!! That would make me furious! What kind of a low stooping shop would do such a thing?? Yeesh, these cars are quite simple, and a good tech would be able to find the problem. If he charged you 676, he should've found the problem and fixed it. OR found the problem, and told you what it is. I know thats definitly NOT right!! Get your money back..

Default 87 Bonnie repaird finally.

Thanks for everyone who made suggestions regarding my running problems. I parked my 87 for a couple of months and finally had her towed to the mechanic. He determined the MAF sensor was faulty, so replaced it, along with the o2 sensor. All in all the bill was around $250.

The 'check engine' light still comes on at times, and faults the EGR code. He told me this would happen, but said it was not going to harm the function of the engine. From what he could tell, the sytem was working fine, but there is a fault somewhere.

The car runs fine now, but the exhaust sort of smells like paint thinner sometimes.

Thanks again all.
