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!

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.
