While the 1981 season gave Petty 3 wins, he felt the season was a failure, and the Regals being ill-handling and poor in reliability. For 1982, he made the move to the Pontiac Grand Prix, with the promise of substantial factory support from Pontiac. 1982 was a repeat of 1978, and no victories were to be had. At first, the Grand Prix behaved much like the Dodge Magnum of 1978, with handling and speed problems. Toward the end of 1982 things improved with several top-10 finishes, which opened the door to a successful 1983 season with three victories, and several top-5 and top-10 finishes. In 1983, he broke his 43-race winless streak from 1982 with a win in the 1983 Carolina 500, barely edging out a young Bill Elliott. After a controversial win at Charlotte, North Carolina in October 1983 (win No. 198), Petty left the race team his father founded for the 1984 season. He spent 84 and 85 driving for Mike Curb before returning to Petty Enterprises in 1986.. How many years was Petty gone for before returning to Petty Enterprises?
