do I need to be relying,

When I pull off the other wires, they all make a difference.

I have changed the fuel filter, plugs and wires, and spark plugs. The #7 misfires.

The truck drives fine when first start out but when it warms up it drives like its jumping in and out of overdrive constantly it also threw p0161 I don't know where to start or if I even should !!

Standerd trany all fluids sposibly changs think its a badd coil pack cosing misfire

when driving my truck vibrates realy bad we just replaced a frame and the bushings on both sides and it still vibrates????????

My heater wont blow hot air.

is there a switch on transmission or where is it located at on this model. it wont start without oulling upon gearshift. is there an ajustment that can be made.
