5KCSTQ Cold Start Problem

Wed Jul 16 07:52:50 EDT 2003

Thanks Ti,

Some more questions:
	1. So is my 88 5KCSTQ a type 44?
	2. Which thermo sensor does the ECU use to time the ICV activity?
	3. Can I use a voltmeter to measure ICV signal and duration
	(with ICV unplugged) or must the ECU see a solenoid load to
	give proper duration of activation?
