The head hasn't been off since I put this engine in a few years ago. It might have been before then, but there were no wires trapped.

I'm wondering if maybe the TPS is flaking out, but it seems like it's the ECU. It's been throwing TPS, AMM, and lean/rich codes.

Hmmm. How to see if the ground is disappearing or the power. Well, power = one wire into the injector harness, the other to ground - if the light stops flashing with the cut-outs, power. If I backprobe with a multimeter and check for resistance to ground, it should skyrocket when the engine cuts out if it's losing ground.

I've cleaned all the ground points I can find - manifold, firewall, both headlights, and passenger footwell.


The fuse was warped, the socket was a little warped, but not too bad. Apparently, it's not unusual.
