Hi i have a 1990 mighty max 2.4l 4cyl 5spd i managed to get the truck running with absolutley no timing marks or anything to go by it took about 5 hours to do the previous owner didnt put the plastic timing belt cover back on when he replaced it so my question is it ran fine when i got it running but two days after that i cranked it up and it sounded like it was misfiring i replaced all ignition and fuel components fuel pump , filter, plugs, wires, distributor, cap ect. and the exhaust sounds choppy sort of like a helicoptor lol i know for sure its not supposed to sound like that what do you guys think it could be considering it was quiet as a mouse two days earlier.im open to any suggestions i checked the vaccum lines as well no leaks and i did a fuel injector treatment also.
