There is no MAF sensor on my car. Based on part listings from AutoZone, it looks like the MAF was not used on 90 or 91s. I'm not sure why this is, since I know newer ones have them.

I have checked both the computer's coolant sensor (it is seperate from the dash gauge) and the Manifold Air Temp sensor (on the back of the plenum) and both are pretty dang close based on the charts in the book.

Update:

After much arguing and manager involvement, they finally started troubleshooting the thing. They concluded that 3 of the injectors on the driver's side were bad (low coil resistance).

So, I'm gonna get out my FSM and check it out to confirm, but based on talking with the tech, it seems pretty reasonable. Of course, they wanted $1900 to do the job (yea, right). So, now it sits in my garage.

Any tips on injector models/brands? I'm not looking to upgrade flow rates or anything (nothing to need a prom reprogram).
