I've had problems with the car idling sometimes, it would shake really bad, and eventually die. Turns out, only one of the two fuel injectors was spraying fuel. So, after thinking it was a problem with the computer or some sensor telling only one fuel injector to spray, I replaced the ECC, TPS, Temp. Sensor, O2 sensor, IAC valve, etc. So, out of desperation, I went out on my own and took the plastic sheathing off of the injector wires, and wouldn't you know it? The white wire and the red wire going to the fuel injectors was just taped there! Who could have done that? Anyway, after loads of money on useless things, it was just that little wire, and now with the thing actually running, I can more accurately diagnose other problems. Good luck with all of your cars problems also, if you have them.

 

Ah ha! The fuel injector connectors screw with a TBI guy too!
