Ok well i found out that i have a single cyl. Misfire. I took a piece of paper, held it over my tail pipe and it sucked the paper in and pushed it out as opposed to just pushing it out.. So the Shop Manager over at the dealership i work at told me it would be in my best interested to just drop 100 bucks and have the Chevy dealership diagnose it and then tell me what needs to be fixed and i think thats what im gonna do.. but its strange because now all of a sudden it seems like while cruising my car doesnt go above 1500rpms even tho ill be doing 50 and accelerating. Also while driving i was accelerating, heard a clunk the pedal became easier to press and the check engine soon light came on but then 2 seconds later the pedal went back to normal and the light turned off... I have no idea.. hopefully the techs over at chevy will.

 

Did you put the paper to both tailpipes or just one?

 

both
