Will a hyperjunk chip in my 90 iroc cause it to act like a bad tps sensor.I have been tring to find this problem for months now.Took it out lastnight and the car acted fine also this moning on the way to work.But that dont mean its fixed its a very intermitent problem.Im about to pull my hair out.

 

Well its been a couple of days now car is great.It had to be that chip.No problems now and no check engine lights lifes good.
