Well,i've been all thru this truck trying to fix a hesitation problem.This problem appears to be related to another symptom of hunting for correct idle speed on cold start.I can't find a vac leak.IAC is new (been thru all the other systems as well).Am down to the computer but am getting no error codes.Was using one of those diagnostic readers with a digital display which has a test function that triggers the computer to activate the relays (and sensors,if I recall correctly).this function worked the first two times I used the thing but has stopped triggering this test.Have heard that you can't just replace the computer - that it has to be "flashed" to work with the vehicle.Can someone tell me anything about this?Thanks
