1993 22re cuts out sporadically. Engine light comes on and it runs a bit rough then clears up and engine light goes off. It has done this for 6 months off and on. I loosened the gas cap and it seemed to help for a while. Went to crank at store yesterday and it cranked initially and then stalled out. Wouldn't crank for 20 minutes or so. Let it sit for 5 to 10 minutes and it cranked up. Engine light is off and it has driven fine since. Thought it might have been the charcoal canister but not sure now. Any advise is appreciated.
