1996 Chevrolet Beretta Z26 3.1L Poor Idle Quality, Misfire
Posted to GM Driveability on 12/8/2005 9 Replies

This thing gets into kind of a galoping idle like it had a vacuum leak and I sprayed propane and carb cleaner all over the engine and none found. Crimped off or plugged vac lines one at a time and still nothing. found the O2 sensor was reading negative volages...
