Thanks Cam,
I was the body shop guy in the family, my brother was the wrench, when he threw gauges on it (old school, I know) I recal either 5.1 or 5.5? He had said that was a tad high but should work fine... he's 6 hours away or I'd go there but cant anytime soon, we did talk about it but he suggested putting on an electric fan to push more air across the fins... that didn't sound like it was the actual problem or he was just spit-balling.
So was the gauges what you meant or is there a machine that will diagnose the electronic control box.
Thanks again for your advice
Terry
