It seems to get worse when it gets warmer. It will drive decently if I just barely press the gas and keep it going but when I try to get over 50 it feels likes its wanting to stall. But when it gets warmer I can't even make it out of first gear cause as soon as I press the gas it stalls out, but it will idle fine in gear or in neutral. I have already replaced the fuel pump and fuel filter, plugs, rotor, wires (all before this problem occurred) and I just recently put in a new Throttle Position Sensor. And I also rebuilt the TBI with new seals and gaskets and cleaned out he old injectors, all before this problem popped up. It was running fine till one day I was going down a hill and down shifting and when I pushed the clutch in to stop it stalled and shut off. I thought It was a fluke and started it back up but that's when the trouble started. It has since shut off when I push the clutch in all the way. I don't think I need a new clutch because it feels fine and doesn't feel like its slipping but I honestly don't know.
