DirtE30 - 1990 BMW 325i

Found out that my throttle cable had about 1/4 - 1/2 inch of slack in in it, but the plastic guide had jammed in sideways so it didn't feel like there was slack, but full throttle was actually like 85% throttle. Tightened that up and went for a test drive.

It feels much much faster now, but I immediately got a flashing CEL on Deceleration. Goes away at WOT. Pulled over a school to check everything was plugged in and read the code. It was a code for a coolant temp sensor (Had this before and cleaning the plug for the TPS fixed it). Car wouldn't start, like not even trying to turn over, cranked fine. I unplugged the TPS and plugged it back in hard and she started again. Took it home and parked it.

A few days later, I drove it to go get lunch and it started sputtering when trying to rev match downshift, then the pedal went completely dead. Then, while not even pushing the pedal down, the revs shot up to about 4-5k, I let out the clutch and finished parking. Got in the car after lunch and drove it home and it stalled out going over a speed bump. No amount of cranking could get it to start, so I started pushing it. I pushed it about 10 feet and tried starting it again, which it did, and then the revs shot up to about 5 grand and I couldn't get it to come back down, so I shut it off and we pushed it to my garage.

Spent some time pulling connectors and cleaning them to no avail, and now the car lies dead in the garage. I noticed the coolant temp sensor that's under the intake shares a loom with the TPS connect and they were stretching each other, so I rerouted those to relieve some stress on them, but that didn't work. When the weather gets better and I find some motivation, I'll find some time to peel back the boot on the connector and make sure the pins are still in, but for some reason, I don't think this is the issue.
