Hello, who can help me please? I have Mazda MPV 2001 couples of days ago I changed sparkplugs I toke out intake manifold, I toke out Air filter housing, and I washed the intake manifold with diesel. After putting all together the engine lost its power, the Over/derive light blinking, it doesn’t run more than 12 miles doesn’t mater how I push the gas pedal, the engine RPM goes up and down, and make coughing. I am waiting for and suggestion, with what I missed up here?
power lost on 2001 Mazda MPV
agree with bak recheck your work. is the ck eng light on? if so scan codes and post so we can adv
The code is: P0122 Throttle/pedal Position Sensor A Circuit Low Input.
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.

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.
