Hi guys! I have an 85 toyota 4wd 22re. I have a severe missfire. Its only running on cylinders #1 and 4! I first replaced all the obvious stuff like plugs and wires, distributer cap, filters, vaccum hoses etc... compression and valves checked out great! I then replaced all four injectors and still the same miss!! Thats when I discovered that with the engine running; I am not reciving a pulsating signal to the #2 and 3 injectors! There is power, but only a constant signal, no pulsating! Could this be the ECU? Anyone have a problem like this before?
Any information at all would be greatly appriciated!!!!! Its driving me crazy!

Thanks so much!!!
