Yes it will work. The onl year that is different is 85.

 

Yes it will work. The only year that is different is 85.

 

Actually, the 85 will work also, I used the same one I've had after I upgraded to the "165" ECM...

Cloud,

The V-8 MAFs from '86-'90 are all Bosch analog units, and should be compatible. As long as the replacement has a five-wire connector that matches the wiring harness, you should be safe. The Bosch P/N is G28D 213 D04, and the GM P/N is 14094712.

Kevin WOULD have to bring up the "conversion" factor, just to confuse things.

If it doesn't work out for you because the MAF is not functional, check into a Wells MAF as a replacement.
