so i just had a new cam put in the truck yesterday and the timing bumped up from 18 - 21*. started it and it ran great, drove it round a little and then parked it. then last night i drove it home and when i get slowed down it just dies. now it wont hold idle, wont start without pushing the pedal, and it still dies when i let off the pedal when i drive it. also it has a real lack of power at WOT. it takes a few seconds before you can feel any kind of power, way longer than normal. I checked every wire, checked for air or fuel leaks and found nothing. i am starting to think that the timing slipped or something. anyone got any ideas?
