2006 Chevrolet Trailblazer LT 4.2L Poor Idle Quality, Stall, Misfire, MIL Lamp on
Towed in by customer. Will start and run but miss on cylinders 4 and 5 all times. Compression, spark, fuel all seem good. Seems to run better when vacuum leak is added. Sensors seem to be reading ok on data, fuel trim staying good, Doesn't run well enough ...
