I recently purchased the 1990 cadillac deville not knowing the full extent of the issues with it. I thought it needed a muffler n found out instead it is misfiring and I was told it needs a whole new exhaust system along with a manifold. My rear manifold bolt is broken off.. can a shop fix this?...
