    I'll assume plugs gapped correctly. With the components you removed, I would suggest retracing your steps. Sounds as if a wire harness was not reconnected or vacuum hoses not reconnected.

    ck wiring at the throttel position sensor. poss not plugged in all the way or you may have bent a tab inside plastic housing. either way a bad connection is very possible

    Thank you much, I believe you are right because I had opened the TPS Throttle Sensor and cleaned it and I turned the inner plastic parts left and right, is that possible that I broke it by turning left and right? By the way, I took out the TPS sensor today and I measured with ohm-meter that gives about 5 volts.
