Hey there everyone,

I'm posting on this forum after being a lurker for awhile, and need some help from the powers that be.

My car is a 1995 E300D, OM606 motor, non-turbo. 240K miles, and I'm in the middle of getting it back to life after the IP took a nose-dive.

I have replaced EVERYTHING in the fuel system, from the tank strainer up to the injectors, which I had digitally balanced, rebuilt and pop-tested with new Bosio nozzles by KermaTDI.

I just got done today with putting the IP back in, and reassembling the motor. I had to wait on the mercedes locking tool for the IP, its critical, and can't be gotten around.... (ask me how I know...)

Anyway, the motor fires up, but I have severe "chuffing" out of the tail pipe, and I think I can hear a slight nailing from one cylinder.

I'll attach video clips of my exhaust and engine, which has the ability to smoke out my garage in roughly 8 seconds right now, but is a LOT better than the last time not using the IP locking tool.

The issue seems to be an overfueling problem, which, starting tomorrow, I'm going to try and isolate to a given cylinder. The question, and the reason for this post, is what would make one cylinder overfuel? Timing?

The replacement IP is a mercedes re-man unit from the benz store in atlanta, and was supposedly bench-tested and checked out.

Any and all help is appreciated guys, if you want the full saga of this project, its over on another forum, and can be found here: 1995 E300d sudden power drop/no-start - Mercedes-Benz Forum

Youtube clips of motor and exhaust today after reassembly are here:
