Is a diesel Lope bad?

What is Lope idle?
Engine lopes at idle. Photo in the Public Domain. We say an engine “lopes” or “surges” at idle when RPMs cycle unsteadily up and down. For example, a car may surge at idle between 600 and 1000 rpm.
Can you drive on Lope tune?
Usually “lope” is only commanded in the idle segment of the map and it has no effect while actually driving. Duramax19 said: it is impossible to drive on. It is way rough to try to drive on so if you get a lope tune dont plan on using it everyday.
Is black smoke bad for a diesel?
Black smoke is partially-burned fuel. An engine that’s running properly will burn all of the diesel fuel completely, making CO2 and water. So black smoke means something is causing the fuel to not burn completely. Not enough air means incomplete fuel combustion.
Do people cam diesels?
Most diesel engines, with some exceptions such as Duramax and some late model Caterpillar and International engines, still use flat tappet camshafts with flat bottom valve lifters rather than roller lifters.
What causes loping idle?
Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.
Can you cam a diesel?
Most diesel engines, with some exceptions such as Duramax and some late model Caterpillar and International engines, still use flat tappet camshafts with flat bottom valve lifters rather than roller lifters. The reasons for this are both economical and practical.
What causes excessive black smoke on a diesel engine?
Over-fueling is the primary cause of black smoke from the exhaust of a heavy duty diesel engine. Excessive oil consumption due to worn valves and valve stem seals, worn or stuck/sluggish rings from deposits, and worn cylinder liners contribute to black smoke.

Why does my engine ” Lope ” when unplugged?
You should notice a change in idling RPMs if that injector is working. Plug back the injector electrical connector and proceed to the next injector. Any injector that doesn’t produce a noticeable change in engine idle when unplugged, is a suspect of failure. Remember that this is a quick and dirty injector balance test.
