Re: Detonation ping

Thanks for the reply! That's another thing I forgot to add! When I was running the 87 it would almost always "diesel" when I would turn the ignition off. With the 91 it doesn't do that. I will look over all the vacuum lines and devises that are hooked up. Last I checked the heater valve on the manifold was indeed working as should but I'll check again. I'll check plugs. Thanks again
