You mean the blue connector going into the black plastic part of the switch? I did clean that twice. Is there a benefit to pulling the black part and cleaning inside where it makes contact with the tumbler? Its only happened three times in the past couple months. One thing I did notice when it happened last was that the key seemed to stick a little when I went to turn it before it wouldn't start.

Also, still no problems on the stability failure front! Very likely was the battery or the body ground (one was a little loose). Still in the wait and see phase on it though.

One of the morals of this story I guess is don't trust a 18 year old kid at the parts store telling you your battery tests fine...

 

Yes, clean the contacts in the switch!

 

Welp, reduced power happened again. This time the only code is P2122.

I’ve cleaned the connectors at least twice. Is there a way to test the tps and pps to see which one may be acting up?

 

I just found a small vacuum leak at the throttle body. Very very small leak but the clip on the hose was broken and I think I could hear a bit of air escaping. Going to temporarily seal it, any chance this could be causing a misread on throttle position for the computer?
