Rbad O2 sensor no codes!! :)
New plugs and wires!
the engine rpm drops to almost a stall, when in gear, at a red light.
I raised the rpm (with the stop screw) high enough to prevent stalling.
When in nuetral or park the RPM is good. BAD SENSOR? Which one?


What else-vacuum leak? Is the computer learning how to operate with a new O2 sensor? Any ideas??
Thanks Jerry

May want to check the IAC valve while you're in there. Clean it out good and what not.
