The LML, on the other hand, ushered in the new era in "clean diesel" technology that brought with it 60 percent new parts while delivering 11 percent higher fuel economy, more power, and greater durability than the LMM model it replaced. Power was at an all-time high coming in at 397hp and 765 pounds of torque, and in order to provide this much power while still keeping pollutants low, GM needed to be able to increase the pressure in the fuel system to levels above what the tried-and-true CP3 could safely deliver. That said, in general, a MAF code is typically generated when theres either too much or too little according to what the ECM thinks there should be at that time. If you live in a warmer area where freezing temperatures are not an issue, you can largely ignore this problem. That lasted about. Tried pumping the primer at the fuel filter.

In the shop for the third time today. The fuel pressure was increased, and the main benefits can be summed up as a more efficient combustion process that resulted in more power and fewer emissions. I understand a leaky FPR can cause this. But thinking about this, if in theory the thermostats were opening prematurely, not allowing the engine to fully warm up, this potentially could cause the EGR to clog because it relies on higher engine temperatures to reduce soot accumulation. Required fields are marked *. Did you check error codes? The electrical gremlins have taken over! San Luis Obispo, CA 93401.

Next, you can run a fuel additive like F-Bomb every time you fuel up which will increase the lubricating properties of diesel to help keep the moving parts inside the CP4 pump lubricated, and finally, you can just ditch the CP4 and eliminate the problem entirely with a CP3 conversion. Therefore, the ideal solution is to prevent it from happening in the first place by regularly changing the fuel filter, using quality fuel, or installing a CP3 retrofit kit.

Turn heat up from low to high motor stalls for millisecond. 700 miles in steady-state driving codes stored in the turbo downpipe largely unchanged, the theme. So what improvements were made to glean nearly 400hp and 765 lb-ft of torque out of the Duramax? This meant more heat could be used in-cylinder to cut down on particulate matter, which culminates in less fuel being required during regeneration intervals (less soot produced by the engine equals less soot accumulation in the DPF). As a result, fuel economy is said to have improved by about 10%. Sometimes the truck just starts bogging and it looses power, no engine light. Lost power steering and had to grab a handful of wheel to not hit a light pole. Any ideas on the cause? When combined with a more efficient fuel burn (less soot), regen cycles occurred less frequently, approximately every 600 to 700 miles (as opposed to 400 miles on the LMM). It has had a o ring kit put in several times in the past what is the recommended repair for the housing when it fails to provide enough pressure to start the truck ?
