Odd vibration
Hi I'm new to this forum and was wondering if y'all could help with my issue.
I have a 1999 F-150 with the 4.2L, my truck seams to have a vibration issue only at a stop. When you go down the road the engine runs fine. She isn't throwing any codes and is idling just fine. I've replaced all the spark plugs, coil pack, wires, engine mounts, trans mount, iac valve, throttle position sensor, valve seals, catalytic converters, crankshaft pulley, throttle body and EGR have been cleaned and I just can't figure it out. Wondering if it's deeper in the motor or not.
