'92 300D power loss and black smoke???

[bnaquin]

I’ve noticed some interesting issues with my “new to me” ’92 300D 2.5Turbo. There are basically two different conditions where I’ve noticed this malfunction.

1. Highway speeds – at 80 MPH and 3200 RPM there is a distinct power loss and a small amount of black smoke from the exhaust. If I back off the accelerator a bit and let the MPH or RPM drop the power returns and the car can again accelerate to the above condition. Again, the power drops out at 80/3200.

2. During a hard acceleration from a stop I’ve noticed the same power loss and smoke at various speeds and RPM’s but it’s by far more intermittent.

In the past few days I ran two cans of the Molly Diesel Purge through the engine and added a can of BG 44K in the fuel tank.

Should I remove and clean the EGR? Any ideas would be very appreciated.

Thanks,

replace your fuel left pump and fuel filters

Just change your fuel filters.
