Re: Misfire and TPS adjustment issues

The lock-up clutch acting like that is a sign, so no idea what it is but the TPS would be suspect.

Harvey.
Talk about odd... after reading your response I went out and moved the pin from the white wire to the red wire (the middle one). I was able to measure the voltage and adjust it to .50 volts exactly. The solenoids were constantly buzzing at .50 volts until I turned the car off and back on again. I assume this is normal?

So is my TPS wired incorrectly? It looks 100% original...

Also, I drove it around the block again and the misfire is still there. Not as bad at idle, but it's now hesitating severely during acceleration. The good (or maybe bad) news is that the CEL light finally popped on. I guess I'll be picking up an OBDII scanner tomorrow...
