when driving my RPM gage stops working and the check engine lite comes on then it will come back and the lite shuts off...any one knows what that means????
 
Could be a bad cam sensor getting ready to let loose. Check the harness connection to make sure it's on good. Run codes too, if you have a scanner.
 
Run your codes. It's been posted on here a few times on how to do it yourself with just a jumper wire. Until you get whatever codes are in there you're just guessing.
