Having problems with your Pontiac Bonneville ?
I have a 92 bonneville ssei supercharge. The problems are that there is a knocking sound, and it seems to be coming from the supercharger, when you speed up the engine it seems to get quieter. I checked the boost sensor and the catalytic convertere. When it is driven the boost sensor gauge jumps over to 10 and there is very little response as far as acceleration. The car also runs hot and dosent cool well. The radiator has no leaks all hoses and clamps were checked the thermostat was replace
