Gas pedal stops working then works again. Shakes violently upon startup
For the past few weeks my truck has been violently shaking upon startup and
then dying. This (so far) has only happened when I have driven the truck a
couple miles that day. When I am able to get the truck running it does a strange
thing where the gas pedal stops working, I could have my foot to the floor and it
goes nowhere. About 3 seconds after it accelerates normal. I had a check
engine light on for which I checked the codes, and did the suggested
maintenance of replacing my MAF. This problem tends to get more severe the
more I drive it in a given day. What could be the culprit? Thanks for any help
