Engine dies when I put it in gear
When I put my truck in gear, reverse or drive, it dies. It is then difficult to re-crank. I have to hold the gas to the floor and let it turn for a while until it finally fires up. Any thoughts?
As background I have had a problem with the transmission not wanting to shift while in drive. I replaced the vaccuum modulator and this helped but it still was not right. So today, thinking I had a vacuum leak, I cut off the end of the vaccuum line going into the modulator and then reattached the line. The end I cut off looked cracked. That is when this latest problem started. I can pull the vaccuum line off completely and it will still crank but dies when I put it in gear. I also tried adjusting the screw on the modulator but that does not help either. when I run the screw in pretty far, like it was when it came from the parts store, it will not crank at all.
Other sypmtoms include the defroster works but it will not change to the panel or the floor. It blows out the defrost no matter what position the switch is in.
