Question about 2002 Chevrolet TrailBlazer
Your ECM has an error code locked in, when there is an error with the Fuel delivery system/ Exhaust system or any related sensors the ECM runs in a lag mode....Transmissions shift harder and slower (its an electric transmition) it may take longer to accellerate up to speed....My advice would be to go to AutoZone Napa or AAP (which ever is in your neck of the wood) and have them scan your ECM with their scan tool.... This will tell you where to start as far as troubleshooting. Also they can clear your check engine light.....this will make your truck run normal again (until the light trips) Hope this helps
