In my quest to find the hesitation problem. I think I have norrowed it down to the CHT.
The car stumbles, spits and backfires when cold. After it gets to operating temp it seems to go away and the car runs pretty darned good. I have done most of all the checks and most everything seems ok.
I checked the resistance on the CHT with the motor cold and it reads approx. 2145. I placed a lead of the ohm meter on the connector of the CHT and placed the other ohm meter lead on the cylinder head for ground.
the book I have says" approx. 3k ohm is good, if it's out of spec replace it".
Is this reading ok? Is the method I used to check the CHT ok or should I check the resistance at the ECU connector?
