Question about 2002 Chevrolet TrailBlazer
Check eng light on,, coad check showed missfire on number 2 cylinder, changed spark plugs... no help???
The code actually means the cylinder is not producing any power.
Could be the plug, injector, coil, or crank sensor. Or a mechanical problem such as a stuck valve.
