Have the front end alignment checked as it may the cause of wandering. With the truck parked and the steering centered, but the engine running, wiggle the steering wheel back and forth while watching the left front wheel.

Any slack here is indicative of slop in the cross-wheel coupling. Hope this helps!

Test that the temperature sending unit in the water system is working properly. When the engine is cold, the computer puts it in cold start mode. Once warmed the temp sensor tells the computer to stop sending excess fuel to the engine and taking the cold start mode to off position. If the sensor is faulty, it stays in cold start mode and keeps dumping excess fuel into the engine causing your situation. Like your running with the choke on after warm-up.

that gray wire is the fuel pump power supply . You cut the wire were an positive tested it ??? An what does that mean . you positive tested it ?
