Now I have a clean throttle body, with a new sensor. van starts and runs better than ever, just need to replace coolant temp sensor, and reset my timing and i think it will be great. Thanks Tim!
. That's certainly not the 1st time I've seen a TPS disconnected. I did this job once & then went check my timing & could get no advance when I pulled the "check engine connector" jumper. I also noticed it was blinking a TPS code. I was like "damn, I got a bad TPS".........that's when I noticed the TPS connector dangling there
. I felt stupid but at least it was an easy fix. All issues were quickly resolved when I plugged that connector back in
