Sprinter 2002
Hi everyone. Hoping somone can help me on here....
I've a 2002 sprinter 311cdi, I was driving the other day when I felt the engine near enough totally die for a split second then just burst back into life and I carried on my journey with no other issues.
The next few days was spot on. Then after a week or so it did it again so I decided to change the diesel filter and made the issue worse! Can drive perfectly fine and tick over fine then all of a sudden. When driving I feel the miss/flat spot and then carried on as normal!
I've checked all my pipes for any air leaks and all are fine. ??????
One thing I read on here was that could possibly the bulbs cause an issue or the sensor on the clutch or brake pedal?
It seams to happen around 2500 revs there or there abouts, and at the same time I did the filter I replaced my front brake pads and found after that the brake lights were sticking on, I also had a stop and tail light out and a rear fog light out all which I replaced, and I also noticed my trailer electrics plug has been broken! No idea when that happened! Any ideas what to try or look at first? Thank you to all in advance. J

My money is on it being an electrical issue rather than fuel.
Clean and improve the earth connections you can see.
