DTC's, Problems & Troubleshooting
First post here, definitely glad I found this place!
I've got a '92 olds 88 with a series 1 in it, about 199k miles on her now.
Start up great, runs great for a about a minute, and then begin the problems.
Starts missing at low rpms at about 25% throttle or more. Cruises fine at all speeds...
