Injector resistance is 15 ohms; equal compresssion all cylinders; good spark all cylinders; code 41 injector drive ciruit code. harness from firewall to injector has no shorts opens or grounds; constant mifire #4 cylinder. wiggled wiring harness still constant missfire. Think his is a computer? What else should I try?

Answer
William: Sounds like a computer problem to me. In the older years of Mitsubishi cars and trucks, the company farmed out the building of their computers to another company that did not build very good ones. With time a piece in these computers will start to leak into the computer; during this time the computers will do all kinds of odd things and then it does kill off the computer. So just to rule out is such problem with your computer, I would have it coded. Being the computer controls everything in the engine, it most likely is the computer, a weak or bad sensor. Hope this helps and good luck! Linda
