Car only runs with the the ect disconnected, if you leave it plugged in it will start but pretty much instantly die. I have replaced the ect with a new one but it has not helped. I havent gotten around to checking the resistance values of the sensor yet, I plan to do so tomorrow, but was looking for any other suggestions if the values check out ok, i.e what to look at next. Thanks in advance, 2.0 16valve 9a with cis motronic.
