My car is a 1991 Toyota Previa 2.2 it has a completely rebuilt engine, brand distributor, new fuel pump and ran great for a long time, but began recently to die intermittently at very low speeds and won't start unless you wait for up to 5 minutes to restart. ..it occasionally will cut out for a split second while driving...sometimes and I I disconnect the terminal and reset the computer to get it started. My tank was cleaned recently, cold start valve cleaned and fuel filter replaced. It is the old style computer (count the flashes) and is impossible to read with a scan tool. I know the systems to check, but don't want to influence your diagnosis.
Scott was right. It was the distributor.
- When they do that off it means I need a new distributor you can get a brand new one at a discount auto parts store I've changed out hundreds of them over the years
How can I test it? This distributor is 2 yrs old. Bought it from rockauto
New or, in your case, not old, doesn't necessarily mean known good. Do as Scotty says. Get it tested.
I just pulled off the cap and rotor button...new condition, no wear....distributor is spectrum premium brand. Bought from rockauto and installed 5k miles ago. Car started and runs normal..how do you test distributor?
My mechanic and electrician are stumped.
What about coolant temperature sensor? The Toyota forum strongly suggests that is my problem, because it seems to be flooding.
