Topic: Anyone had this problem, Missing on 2 cylinders?

[wayland]

I installed a 3vze V6 engine in my 1991 Toyota. The engine is out of a 1994 Toyota T100, I have run into a problem where it is time for help. I have number 2 and 5 cylinder missing. The compression reads 120 lbs. I installed a new dist. cap, rotor, plugs new plug wires, the spark is a  blue and strong. Next I installed 2 new injectors, Still have the miss, Next I installed the temp sensor.  Now am at the point, I checked the injectors again with a 12 volt test light, they are firing good. Anyone know what might be causing the engine to miss on 2 cylinders? Thanks

Are you saying that you have 120 on those two cylinders or all 6. Is it possible that you have those two wires switched?  If not, it seems as though you have covered your bases on external causes.  I would start thinking about the possibility of a burnt valve.

No crossed wires, I tripled checked, each of the missing cylinders has 120 lbs each, A burnt value would let air through and not hold 120 lbs so i know that is not the problem. My thinking is maybe the computer is not sending the right signal to the injectors on time. Reading a lot of post this 2 cylinders missing is a common problem on 3vze engines. Hope someone knows the answer. Thanks,
