Hi, I just noticed that my car has its power and kick back right after I start the car when its idling higher.
The car would run fast, but would hesitate from time to time.
After about 5mins. the idle falls down and the car is a dog off the line.

I have a new bosch sensor 1 wire, with headers. I never had problems with it before, but could that be it ?(changed it after I had my hesitation problem).

Also, I will be datalogging since I don't know what the heck is wrong with my car.

Also, it downshifts way to late from 3rd to 2nd. What would you say would do that. Note I did readjust the TV cable.

I also have a bad rear caliper and I can hear it scrape against the rotor sometimes. I will replace that, but could this cause a problem with trying to do a burnout??

Thanks soo much.
