check engine light on? whens the last time you did a tune up?

 

[explorer_92]

no check engine light, i even went through 1 by 1 and unplugged maf sensor,air idle control motor,and tps sensor every one caused a check engine light.but once i plugged them in no light,doesnt sound like a fuel filter i can rev it up constantly no hesitation, now when the problem 1st started a month ago i changed my tps sensor and it worked for a month.. back too the same problem

Maybe your torque converter isn't unlocking.

Modulator? Any ATF loss? or vacuum at intake?

Good luck
