Having problems with a 2000 GTP. After sitting for 3 hours started back up and instantly died. Restarted with black smoke out the exhaust and idle fluctuating from 500-1500 then dies. Could keep running by reving engine but when tried to drive engine died when let off accelerator. No check engine light. Happened at lake so I have to trailer it to shop. would like to see if anyone has any ideas.
Thanks
K
