If the CEL is on, get the codes scanned first. It could be any number of things. For example, bad MAP sensor, Bad MAF sensor, bad CPS, dirty throttle body, dirty IAC, on and on. The code should give you a place to start. You can post the codes here and someone will tell you what they mean.


Check crankshaft position sensor....
