My 99 park Ave just crapped out on my in the strangest way, was getting on the highway and as I accelerated I felt my gas pedal go soft and It was not working and as I got over into the emergency lane my steering locked up and all my lights dimmed out and once I put it into park my lights went normal and I shut the engine off and tried to start it again and I smelled a strange smell and it would turn over then just shut off each time doing a weird smell not sure what is wrong to be able to fix it
