I am also facing the issue of me touching something I shouldn't have. My 1987 B2 will start and run fine for 30s before flat-out dying. This was after I had messed with my TPS. Hopefully, this fixes it. What do I do if I can't get it to warm up because it keeps dying?



I'm worried about this too. Does anyone have any recommendations if I come across this? Can I adjust the voltage of the TPS without touching the the Idle screw?
Will it stay running with your foot on the throttle?

id make another thread for this issue itll get more attention.

Update: I cannot stress this enough, DONT TOUCH THE TPS. I finally fixed my problem. Before, it was struggling to stay at 45, now I can do 75 up a hill no problem. It felt as if it wasn't able to change gears. I probed the ground and the signal wire from the TPS and measured it to be ~0.74v. I loosened the screws on the TPS and tilted it until I couldn't turn it any farther to increase the voltage to ~0.84v, after tightening the screws and resetting the ECU by unplugging the battery for a few minutes it ran like new! I'm gonna try to the get the voltage 0.9v and the idle RPM to 700 and see if that improves it any further.

I know the oil weight is wrong on this label but is the Idle RPM correct ? (1990 2.9, AT)
