I guess you heard the one about the the three guys in car that would not start? An electrical engineer, a mechanical engneer and a Microsoft computer software engineer.
The EE wanted to replace the air mass sensor, ECU and trouble shoot the ignition system.
The ME wanted to replace the injectors and check fuel pump pressure.
The Microsoft CE wanted to close all the windows and then open them again.
I know thats weak but hey what do you want at 1:30 am?
