Blacktop problem

[aarong420]

hey, sorry to bring back this topic, but i need to know how to diagnose the problem.
Im having the same problem with my BT 20V, and i think it can very well be the same starter signal problem. The reason i think so, is because when the electrician was wiring my car (ECU was already wired, but fusebox and internal wires needed to be connected) i noticed that when i switched off the car, sometimes it wouldnt switch off!!!. He supposedly fixed the problem and i havent gotten the problem since. But i DO however get this same bogging problem. If giving a little more gas, or more commonly with decelerating slightly, it gives a bog, and i believe im losing power on the whole. It's also very sluggish on acceleration from under 4K.
Im going to do the tests stated above later today, so with that said ill update whoever seeks interest in helping me.
Thanks.
