shifted from park to drive or reverse? it is an 88 jeep with a 91 engine in it, it was installed in an auto shop and ran great for a few weeks, but now it starts and runs fine , but when it is shifted into gear it stalls every time
Go back to the shop--the problems are too many to mention here. No one can guess at what it may be. Stop wasting time and get it to the shop that rebuilt and installed the motor. Any GOOD shop should have given you a warranty for that motor--it should be fixed for free.
