Trailblazer...What's wrong? I have a 2004 Chevy Trailblazer and every so often (becoming more frequent) The Check Engine light will flash on for a second or two and then go off. During this time, the gauges (RPM, MPH, etc...) Jump and go wacky and the engine seems to rev. It has been in the shop multiple times and no problem has ever been found. The code is never stored in the system. Was wondering if anyone else has this issue and if so, What the heck is the problem and is this harming my car?
