now since i have been running the car with 42 my car sputters until i get up in the rpms. i still havent had time or money for a tune if thats whats causing my problem. sometimes at idle if i tap the gas it will stall out. i need to check my plug gap since i think i forgot to regap them to .040. i dont know if they are fouled. i have new plug wires and a coil along with an ignition module. not sure if its my dizzy or pickup. when it does stall out. somtimes i can start it back up by holding the gas pedal down to shut off fuel to the injectors and sometimes it wont start until a few minutes later. im kinda stumped on this one
