Update:
The car is running like crap. It starts fine, but smells rich. Then, after it warms up, it's like a light switch. The timing goes wacky (on the PMS screen it varies from 15-ish to 32 degrees at idle!) and the rpm drops to 550 and it backfires.
Sometimes, if I shut it off and start it again, it acts normally for a while, then the condition returns. My brand new 02's read .00vdc at idle. As you might guess, it drives poorly. Hesitation, etc.
I got my wideband 02 bung welded on today and will install the wideband tomorrow or Saturday. The only code is 91, 02's reading lean...
thanks for any tips...
