05 Trailblazer
I have an 05 Trailblazer that is running rough. ROMs going crazy. Acts like stuck in neutral. Can get it to go to 3rd gear. Then have to let off gas reduce speed and it shifts to next gear. Computer gave codes for 02 sensor fuse, cylinder 4 misfiring, low coolant temp and air register issue. Fuse looks good. Didn't know what to do for last 2 so changed cylinder 4 coil and plug. ( never been changed- I know I shoulda done all!!))
also plug had some oil on it. This fixed the issue for about 10-15 mins then it started again. Never got as bad as 1st time, could actually go 55 mph but still had RPM whining sound. If anybody has any suggestions, all are welcome and appreciated. !!
