Ok it's a '91 Stealth Base. Ran into a problem where the car wouldn't idle once it got warmed up. When you let off the gas and started engine braking the check engine light would come on when it got down to maybe 2500rpm and then go off around 1500 rpm or whenever you got back in the gas. Other than that it drove fine for the most part. So yesterday i was driving along maybe 45mph in 5th and it just died completely. It cranks over but doesn't even try to start. I've checked every fuse on the car. There is no spark getting to the spark plugs. Any ideas?
