Question about 1988 Ford F 150
More than likely a vacuum leak. the pcv hoses on these are known to leak as well as the intake gaskets. need to look at the freeze frame data on a scanner and see if it set the codes when it was first cranked, if so its prolly intake gaskets as they leak and **** air when the engine is cold. a vacuum leak would more than likey set it anytime
