An unplugged/non-functioning CTS (as well as the CKP) will result in a no-start condition. Both sensors are the main inputs for the ECM

Im pretty sure the blue cts (coolant sensor for the ecu) has to be unplugged to set ignition timing, and the black cts is just for the gauge.

This is correct, however you may need to play with the throttle to keep the engine running once the blue CTS is unplugged. Gotta hold the engine at ~ 2500 RPM to set the timing anyhow...

Once ignition timing and idle are correctly set the engine "may" idle roughly with the CTS unplugged.

your idle is set incorrectly. You need to adjust your idle screw. Once this is correct then your car will idle with the blue cts unplugged.

Check your bentley for the procedure i dont do it as per bentley i use a different way which isnt liked on the forums but my idle is purrrrrfect

I'll give it a shot, thanks.

Or your ignition timing is that far off. The screw doesn't do anything unless you have already unplugged that sensor and prepped the computer by revving the motor. I think you should adjust the distributor until the idle rises and then try unplugging the sensor and look at your timing. In preparation for adjusting the screw though, make sure you replace the screw or at least the oring.

Well I revved it up and unplugged it and it was still running, just died when I let off the throttle. Im going to get ahold of a g60 bentley and get all squared away the proper way. Thanks for the input.
