I have a 1989 Tempo, 2.3L EFI, that has just started stalling. Had the battery out for an hour or so, which I'm guessing has allowed the computer to reset thus exposing this problem.
It starts, runs. idles and accelerates fine, but, idle drops to the point it will stall when stopping and when shifting into P/R. This seems to happen more so when the car is warmed up, when cold, idle speed is high enough to prevent stalling.
Should I start checking for vacuum problems/leaks, or is it more likely a faulty sensor?
Thanks in advance for any advice or ideas.
