Truck started acting like the turbo quit working. I have taken the carbs off three times and cleaned them with carb cleaner and compressed air. Next to the rev limit thing, it starts terribly bad; it takes a second. warm ,have you tried to run it on a can of diesel to see if it improves and post some figures up over the weekend. It then stays at a 1100-1300 RPM high idle for a couple minutes before reducing to a sub-1000 RPM idle. 2) The 2000 rpm limit is strange. So for a 2600 rpm red line you are looking about 2100, for a 3000 rpm red line 2400 rpm, and so on. 0 I just spent $8,000 to repair in the past three months. Next problem when reading specs is - what type of RPMs and what type of degrees - pump or engine? Injection pumps run 1/2 engine speed so. Drove truck and it was not shifting correctlywould not go over 40mph. Removing the rev limiter. If you can't get hold of a back pressure gauge, you can connect a vacuum gauge to a manifold port, rev the engine up to 2000 rpm and see if if the vacuum reading starts moving toward positive pressure. The line of MSD 6-Series Ignitions are the most popular aftermarket ignitions in the world due to our race-proven performance on the track and our reliability on the street!. In OD at 55 mph (engine speed below 2000), it runs smoothly but has no power to run up hill or into a head wind. Leave it for a few hours - say go to the cinema. Anybody had this problem? 2005 duramax wont rev over 2000rpm.
