Question about 1991 Toyota MR2
My 1991 mr2 usually idles around 2500rpms. seems to rev up on its own while shifting but not with your foot on the accelerator. changed the tps now idles around 2000-2500rpm but occasionally fluctuates between 1200-1800 erratically until you put it in gear and move the car then it seems to straighten out. this last problem did not happen until after the tps was changed (battery disconected while doing so to allow cpu to reset, it reset but wrong apparently). what gives?
Sounds like your idle speed is way too high, should be somewhere around 800-1200 rpms. I would check for vacuum leaks.
