mcm280turbo

I think you miss understood me. Everything is good when it is cool. When it is hot and it is restarted after stalling it miss fires real bad and that is when it stalls under any load.

It will start in just a few minutes but misfires real bad. Once it under any load it does the same thing. Once it cools all the way it will run fine foe a while.

I bought a 260Z that had a early 280ZX Turbo engine put in it. The car will starts and runs fine while it is cool out. Once it has had time to warm up it begins to have a miss a small miss..It now has started to stall for no reason. I let it sit and it will start fine. I have started with the basics Fuel filter, pressure regulator, coil, plugs, water temp sensor and checked and cleaned the connections at the ECU. At this point I have to believe that it is electrical that only happens once it has warmed up. Any suggestions would be greatly appreciate..
