So I have a 99 GST. When I start my car up in the morning, the idle will jump to about 3k until the car heats up and then it hovers around 600rpm. If I put the car in reverse it goes to around 200 and sometimes cuts off. It will also jump up and down throughout the day.
I took the car to Mitsubishi since there is one down the street and they said it was my Throttlebody so my question is can a bad TB cause this type of behavior?
I don't want to replace that if its not the issue.
Also they want 420 for an OEM TB. What would you suggest as a good upgrade from the OEM TB? If I have to replace it I might as well upgrade it now.
