runs rough but no codes

Asked by Kevin Jul 11, 2019 at 08:06 PM about the 2005 Chevrolet Trailblazer LS 4WD

Question type: Maintenance & Repair

An answer to a similar question and it said to look for something that would
mimic a misfire i.e. motor mounts, although it feels like a misfire when I'm in
the driver seat but sounds like it's running fine when I'm standing over the
engine but it has stalled while I was waiting for a light to change, also when I
start my day early in the morning everything is fine, I can drive for hours
without any problems until I turn on the A/C, and feels like misfire again

Clean the throttle body, first thing you should do. Remove fuses #10 and #28 prior to removal of throttle body. Clean with a rag and nylon brush only, using a sensor safe solution similar to Seafoam spray.
