First you should know the M42 does not use a MAF but an AFM. Its a huge difference. You can send your AFM to us to be refurbished. We've refurbished hundreds of AFM's with great success. You will noticed increased engine power, better idle, and ability to pass smog easier. Email me bavrest@gmail.com

How, specifically, did you determine that the AFM is bad?

your mechanic could be wrong, yknow. loss of power huh?

go through the basics (check TPS resistance, fuel system tests, air filter, ignition system)

alot of people are quick to point a finger at whatever but those are the same people who buy new parts that dont solve their problem.

Wouldnt it be plausible he's already gone through this stuff?

It's pretty easy to test the AFM with an ohmmeter- they're painfully basic, electrically.

I find it's a lot easier to do out of the car- Pelican Parts has a good writeup on it.

What I do,

It's difficult to diagnose a problem with such little information to go on. The M42 was pretty advanced for 1991 and there are a lot of things that can affect driveability and power. What all has been replaced and what all symptoms are you experiencing?
