Hi all, Just got a '92 Civic VX Hatch yesterday as a daily commuter. All stock except aftermarket exhaust and stereo head unit. Prior to my purchase the O2 sensor was replaced and cleaned out the EGT I think.
Runs well except this morning it had a bit of an idle waver by about 500rpm but it wasn't consistent. Sometimes when coming to a stop it would do it and sometimes not.
The other is when cruising on the freeway about 70MPH or 21-2200 rpm it will seem to get a surge in power and then settle back down. Was hard to keep a steady cruise over 70 and under 75.
