Took it to O'reillys to ck the diagnostics and was told that it was the variable camshaft timing cylinoid- However I read that before changing this part to possibly ck the engine oil to make sure that it is not dirty!? I was due for an oil change two weeks ago and my change engine oil light has not come on yet- has anyone else had this issue with it being as simple as changing the oil? I get really crappy gas mileage (like maybe 8-9 miles to a gallon)- HELP! Love my Trailblazer, hate that the engine light is on and that my gas mileage is soooo crappy!
