Having problems with your Chevrolet TrailBlazer EXT ?
Could a misfire on #4 be an ignition coil? I have a 2005 V8 trailblazer
\015 I have replaced plugs and wires and had the injector checked but comes up #4 misfire...the mechanic wants to check rocker arm but was wondering if the ignition coil could be the culprit. It is ticking and running VERY rough and a loss of power ...Thanks for any help...\015
Yes. Replace the ignition coil pack for #4 plug wire.
