Question type: Maintenance & Repair

I am having problems with my 5.7. It runs fine at
an idle but when you give it gas it misses and revs

wires, cap, and butten, but still has the same

May be a bad fuel pump, should check fuel pressure, change the fuel filter first. Fuel pressure should be 9 to 13 lbs. Also may have dirty or faulty injectors. Another cause could be the coil, you can have that tested at Auto Zone.

U need to have someone put it in drive and hold the brakes and spin the cap clockwise
