I have a 91 toyota celica that surges from idle to about 2,000 rpm?s constantly. I have replaced intake manifold gasket, vacuum hoses, air intake hose, throttle body, IAC valve, throttle position sensor, oxygen sensor, vacuum sensor, heat sensor, cold start valve, fuel injectors, fuel regulator, fuel filter, fuel pump, ECM, distributor, igniter, coil, timing belt, done compression check cleaned and checked all electrical connections, checked grounds, I dont know of anything else to replace, nothing helps, computer does not show any codes. Anyone got any ideas. Thanks : :roll:
