Question about 1991 Toyota Camry
While driving at moderate to highway speeds, the engine seems to stumble (****). Have replaced plugs, wires, cap, & rotor. Have run several bottles of fuel system cleaner, all without success. Seems to be more severe when warm. What else should I check? Help!
SOURCE: truck stumbles just off idle
may need to have a fuel injection service,but when i worked at chevrolet i believe those year trucks were having a problem with the throttle body sticking

O2 sensors and cat monitors will not cause this condition, try cleaning the MAF sensor, CRC chemicals makes the special spray, avail at most auto parts stores like Kragen.

Well, I would replace the air filter, make sure the air hose from the air filter to the intake is not kinked or blocked and check for vacuum leaks. If these are all fine, I would check the fuel pressure as it is possible the pump is weak and not supplying enough fuel.

Did you ever do a tune up? If not you need to change the spark plugs pvc if you have one,some do and some dont anymore.also change the spark plug wires.This is where you have to start,even if your car was in a shop.Then you go from there if this does not fix your problem take to a good repair shop.
