i have a a 91 r/t that wont start at times and wont stay running when it does start. I replace the leaky caps on the ecu which there wasn't any board damage and i made sure my MAF is good as well it has a new fuel pump and filter and spark plugs as well. most times if it wont start i can put my hand over the throttle body and it will start up but i can't rev it up because it will cut out and die. I don't know what else to do I just want to drive this car
