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 Posted / edited by AnonymousUser on : 20-05-2019
