ok the problem happens around the beginning of the video what all that happens -lights dim -motor feels like it wants to shut off -and the idle is rough -it also pisses me off YouTube - 98 f150 idle problem
When i slam on the gas it hauls ass like normal no problem at all it just does this when I'm stopping sometimes It has new plugs and wires Could a alternator cause this
my truck every now and then surges idleing... like it goes from 800-300 and back and forth.... needs to be cleaned just havent done it yet hahaha but try cleaning it...
What ryan said. try cleaning it. head up to the auto store and grab a can of throttle body cleaner and clean your TB out real good and your IAC. i would even clean my MAF sensor too but not with the same cleaner! MAF cleaner will do the trick.
