I have a 1991 Accord, 5 Speed, that is starting to stall when I start it. The engine revs up but then drops down quickly and stalls immediately after starting the car. If I rev the gas a little I can usually put it in first gear and go and not have any other noticeable problems. The car has been idle for several months as I needed money to replace the clutch and flywheel which just got finished this last Sunday. Any ideas on what could be causing it?
