Help w/ father son project. Have an '83 320i that has current tune up. Sputters and lurches after shifting can push through after shifting with gas pedal. Then does it again on next shift. Worse in 2nd and 3rd (5spd) seems better in 4th and 5th seems to pulse while driving at hwy speed. AFM and idle combo problem? Seems worse now w/ warmer weather moving in. Any advice is appreciated.
