Yes. Car is an 87 GTA, but engine/trans are a 350 5.7L TPI out of an 89.
The MAFS was a cheaper aftermarket that I bought since money's tight right now, but after the rev'ing started, I used some MAFS cleaner on the old one that I took out, which is a Bosch. Rev'ing stopped, but some of the original issues came back (slower to crank and smoked a good bit when I cranked it up; both had stopped with the new MAFS). Was able to take it a few miles down the road and back with no performance issues, so I think it's holding up, but just bought a Delphi MAFS to hopefully be done with it. Will return the cheap one and keep the older Bosch as a backup in a pinch.
