Whats up everyone. I am havin a major problem. I have just put a thumpr cam in my 79 mustang. I cranked at up did the break-in procedure, but everytime that i put the car in reverse or drive it goes dead, and when i try to just hold it to the floor try to back up it will hesitate like and go dead. As long as it is just in park idlin it is fine everything is good. So if anybody can help me out I will be very glad. Thanks everyone.
