well since my last post, heres whats up. my Check Engine Light keeps coming on and off, my idle still sucks (from 400-800 up and down) and my car is starting to vibrate. it also hesitates when im making boost. um i cant get any codes to show up except for once i got ego rich and ego lean. everyone told me its a camshaft sensor or o2 sensors and im fixing to replace them. would that make the car vibrate too? thanks guys i hope the Camshaft sensor and o2 sensors help and the stupid CEL goes off!

Run a search on how to clean your maf and make sure the wires attached to it are nice and clean and making good contact. Seriously, it makes a difference.

Bad O2 sensors can cause surging, a cam sensor causes bucking and weird tach bouncing, not so much surging. I started the car once without plugging in the clip on the MAF once and got those symptoms. A lot of black smoke sometimes out of the exhaust.
