Ok I have an 874runner with a fuel injected 4 cylinder 22re and a manual trans. My problem is that after the vehicle has warmed up to operating tempature I am expierencing a miss I checked the trouble codes and they indicate the igniter has missed 4 or more times. I am sure it is not the igniter as this is the third when the second one did the same thing as the first I replaced I have also replaced the distributor and it's magnetic pickup. I have changed all the plugs and plug wires as well as the cap and rotor I have check numerous grounds and pwr leads with no luck. Does anyone have any idea what could cause this? Could a Temp. Sensor be lyning to the ECM and cause the igniter to not go off? could the warm engine just make a problem that is unoticable cold show up? If you help my wife will be happy as I will have regained my sanity however my shrink won't be to happy lol.
