Weird violent bouncing.

I have had a similar issue on a 97 and it was the throttle return spring, odd but replaced them and no more issues.

I believe there was a TSB or recall and the dealer will repair it for free, at least that was the case about 6 years ago.

I’ve read about that recall, and even tried to buy the parts kit. Ended up buying a kit from Geno’s. I bet the stealership’s head would explode of they got a look at this psychobilly Cadillac! Has two VINs visible in the windshield

Oops. Didn’t know that was a bad word. Funny thing to bleep. Nothing illegal about the truck, just a cab swap.
