Can the cars computer fire the plugs at the wrong time causing an open air situation in the cylinders? I have a 91 mitsubishi 3.0 twin turbo engine. My car steadily lost power and died in a quarter of a mile from where I first started it. It has spark, compression, fuel, all the sensors have been tested and replaced, (cam positioning sensor ect. new injectors, fuel pump and regulator, ignition relay, coils and sensor,timing belt, (which is brand new and all 5 marks are on the button everytime it's checked). The exhaust was dropped in case of plugged converters. I inspected the inside of the ecu and didin't find any sign of leakage or water damage. The engine was a JDM I bought. I dropped it in and it started right up. I ran it at my work for 5 hours a day for a week. It ran great. I was taking it home and it started losing power until it wouldn't go anymore under load. After it stalled it wouldn't start up again. That's when I had all those things done to it' Even after spraying ether into the intake it refuses to even fart or backfire, yet it has good spark, fuel and 160lbs of compression in the cylinders. This car is driving me nuts. I'm afraid to tow it to a shop because they might say it's something that it's not and i really can't afford a lot of money right now. If you have any idea whats going on i would really appreciate it. thanks rick
