Help!!!! with miss
About a month ago I submitted a thread about a miss that I 'm having w/ my truck. It doesn't do it all the time, but sometimes more than others. It seems that for a second, someone turns the key off. It also will idle down & stall out. I'm running out of ideas. Changed plugs, cap, rotor, wires, computer, intake gasket, cleaned throttle body and replaced gasket, ran it w/ EGR vacuum plugged & unplugged,fuel pressure regulator, fuel pump, checked fuel pressure. No check engine light, no codes in computer. Spark plugs wires are routed correctly. Could a faulty ing switch cause this? Truck has 265,000 miles, w/ approx 40,000 miles on reman engine. Help!!!!

It is a part to half throttle surge. I cleaned IAC when I cleaned throttle body, also replaced TPS. The fuel mileage has gone way down 11-13 highway.Would a faulty KS cause this? Could it be unplugged to test?
