My daughter left house and made it about 2 miles. Truck was fine before but now you have to feather the gas to get it to go. If you floor it , it sounds like an old quadrajet for a second but goes no where. It also has a rattle, cat or torque converter, flywheel? All just started. Scanned got a MAF sensor O2 sensor and a shift solenoid code. Anyone experienced this problem before or am I just lucky?!! Probably help if you knew what was in it! 4.3 4x4 crew cab.
Any help would be appreciated.

Take the intake boot off the throtle body and see if it has oil on it, that will give you a place to start. The PCV valve could be broke, causing oil to shoot up the breather line into the throttle body. it can also make its way down the intake duct and case the MAF sensor to malfunction. The result of burned oil in the engine can cause the o2 sensors to fire a code as well.
