1993 suburban c1500 5.7L. Bought about a month ago and getting gremlins out of it. When cold, the rpm surge and seems like big vacuum leak. But read some posts and gave me idea to unplug newly installed O2 sensor. And yes it made the surge go away.
Once I drive and it warms up the surge goes away.
Anything I can do to get around having to wait for O2 sensor to warm up?
Thanks
