Thanks for the help guys. It has an EEC 4 type plug. I got code 13 and 33. Can't control idle and EGR not opening. I stuck some seafoam in the tank and was going to let it run a while. Forgot to get the carb cleaner to spray into throttle body when it stumbles so I took off for the garage. I tried to hurry but just as I got back it died. I tried to spray some into it and tried to start it. Doesn't even try to start. After a couple times trying, when I turned off the key it kind of stumbled and exhaust shot back out of the intake hose from the air cleaner. I thought that was kind of odd.
