E 300-D missing at cruise speed
1997 E-300 D has developed a missing sensation after it warms up and at cruising speed. It does not do this when you accelerate hard.
The dealer suggested replacing the EGR valve and two vacuum transducers. They said it was about 7 hours of labor...not a cheap fix at around $1200.
Does the fix make sense and how hard is it to replace an EGR and the transducers?
