M20 rev problems

[laz]

TPS on my car tests ok according to the Bentley's test. Too late to start up the car to check fuel pressure ... the neighbor will complain.

I swapped the AFM from my good car this morning and that solved the problem.

I checked simple resistance on the rightmost 2 pins of the connector. Both of them progressed linearly from around ~5kOhm to ~7kOhm at the end of travel. Both went a bit non-linear at the end of the range before settling down. The bad one went more non-linear, and had a spot where it would go infinite impedance/no connectivity. So, I suspect the ECU was shutting things down when it got no voltage from the AFM.

Im having the same problem on my car, it started doing this last week, but it wont rev past 4.5k.

I have a spare afm that came with the car when I bought it, Im going to swap it out and see what happens.
