{"text":"Hi, I may of figured out problem of random miss, but need further info from you. I changed throttle position sensor in foot pedal about 2 years ago, Random miss has been around since then. I was recently told by justanwswer, that throttle sensor needs to be calibrated when changed... is this true? I explained the idle with cruise on, is much worse than using just the pedal. He stated that ecm uses different parameters for cruise and foot, and the ecm must be recalibrated using Insite, after changing sensors. Does this sound right? I don’t need to be wasting money on chasing ghosts. Thanks for your input.","pics":"[]","canComment":true}
