Question type: Maintenance & Repair

The wife was driving our original 1986 Mustang 5.0. She started the car to
leave work and it began to idle very fast. She went to shut it down and it would
not turn off it kept running. The battery died and it quit running. It's a 5 sp. So
that's where we are. Any one ever come across this problem and what is the
fix. Thanks.

Not sure what could cause it to not shut off when key is not in the ignition. But the MAF sencor is what regulates the engine and tells it to throttle up and idle. Mass air flow and its near the air filter with a plug hanging out of it. Or the computer is on the fritz and its malfunctioning telling the MAFto tthrottle up. WWon'tknow until yyou put a computer on it to tell what'sthe pproblem
