Engine Performance problem
2004 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 91000 miles
I have a 2004 Trailblazer and I have always been happy with the performance until a about a month ago. When I start up the vehicle in morning it runs rough, so after it has warmed I notice as I am driving I do not have the pick up and go that it used to. I have changed the fuel filter, air filter. I want to know if I should change spark plugs? I have read a number of posts that say that it may be the Idle air control valve and/or the Cam Actuator Solenoid. Not sure if I should try to replace these as well.
have the same problem?
