In 1990, McLaughlin returned to the Busch Series, driving the No. 51
Coors Extra Gold Oldsmobile in six races. Despite two wrecks, McLaughlin had two top-five finishes and caught the eye of many in the sport. He ran eight races the following season, but was unable to duplicate his success. After part-time runs in 1992 and 1993, McLaughlin finally ran his first full-time schedule in the Busch Series in 1994, driving the No. 34
Fiddle Faddle Chevrolet for
Cicci-Welliver Racing. Despite not making two races, McLaughlin posted three top-fives and finished 13th in points. He also ran two
Winston Cup races for Cicci-Welliver that year, finishing 22nd and 27th at
New Hampshire and
Watkins Glen, respectively. In 1995, McLaughlin got his first taste of Victory Lane, winning the
GM Goodwrench/Delco 200 at Dover, and collected thirteen additional top-tens on his way to a third place points run. After a winless 1996, McLaughlin won twice in 1997 (including at his hometrack at Watkins Glen) and was named the series' Most Popular Driver. 1998 saw him add
Goulds Pumps as his primary sponsor, and he won two more races, and matched his career-best finish of third in points. After going winless in 1999, McLaughlin shockingly announced he would depart from Cicci-Welliver at the season's end, citing a need for a change. He and Goulds left for the No. 48 Chevy fielded by
Innovative Motorsports in 2000. Unfortunately, the season was a struggle and McLaughlin could not get the cars up to speed. Despite two fifth place finishes, McLaughlin jumped ship just weeks before the start of the 2001 season to the unsponsored No. 20 owned by
Joe Gibbs Racing. McLaughlin shocked the NASCAR world by winning the
NASCAR Subway 300 at Talladega, albeit controversially. Despite the win, the team could not continue to run unsponsored, and McLaughlin moved over to the
MBNA No. 18 for the remainder of the season. He finished seventh in points. In 2001, McLaughlin was
Tony Stewart's back-up driver for the
Coca-Cola 600. Stewart was running the
Indy 500 the same day and McLaughlin was to have started the race if Stewart did not arrive on time. Stewart eventually arrived in Charlotte just minutes before the command to start engines and finished third. == Struggles and retirement from driving ==
