I have a question about my maf. I have gta 89 with 350 tpi and a have a very lean fuel mixture. I dont have any performance above 3500 rpm and i have backfire in my intake when the engine is cold. The serial number of my maf show me that is one use on corvette 86-87. My computer dont give me any code.

I consider changing my maf for a good one. Do you think this will resolve my problem?

thanks,

 

Try disconnecting the electrical connector going to the MAF and see if the backfiring, etc., disappears.

If it does, swap the MAF Power and MAF Burnoff relays first, see if things change.

I'm not aware of a difference in MAF's for the Corvette and F-Body, but '86-89 MAF's for F-Bodies will interchange.

 

thanks for your comments, anyone else??

 

I really really need your help fast please!!!

 

Well, did you try what I suggested, if so what were the results?
