I've got an 05 chevy classic. It has the 2.2 cylinder motor in it. Saturday night all the sudden it started to loose power as I was out driving around. You put it to the floor and it doesn't wanna do anything. Won't even go over 2,000 rpms. Then after 10-15 minutes it started running fine again. Last night it started doing it again. Won't go over 2,000 rpms and just has no power at all. It came out of it again, but now since then its staying to the no power. It starts up great and idles great. It doesn't over heat as of now. I ran the engine heat through it because someone told me maybe gel in the fuel lines. That wasn't the issue. What do you guys think it could be?
