CK engine light after moderate acceleration
2003 PT Cruiser GT (turbo): The engine runs great but the check engine light comes on about a minute after I accelerate from 40-70 mph or from 50-75 mph, either going on an on-ramp or while passing. Lots of acceleration, but then the light comes on about a minute later (maybe less). I can clear the light by disconnecting the negative battery terminal, but the next time I punch the throttle on the highway, the light comes on again. The engine temp gauge usually reads just below 50%. Any ideas?
