Misfiring happens when one of the cylinders of an engine’s combustion cycle fails. Įngine surging is when an engine starts easily and accelerates smoothly, however after a few minutes at a steady speed, it either surges in speed or misfires. “Surging” does not refer to a knocking engine or one that idles rough or stalls. ![]() ![]() Engine Surging: Symptoms Surging or misfiringĮngine surging is different from a difficult start or a no-start problem.

The good news is in many cases, engine surging can be repaired with little costs. You might come across either engine surging at idle or car surging while driving. This issue is often referred to as engine surging, or rapid acceleration or deceleration cycles. The slightest malfunction in any part will make an engine’s cycles deviate from what is optimal, impeding the engine’s performance. The internal combustion engine relies on the precise cyclical operations of a multitude of parts, including precise air/fuel mixture, spark timing and exhaust management. A common malfunction you will likely encounter is engine surging, and knowing how to fix this in under 45 minutes is a maintenance tip you must master early. The car sounds as though it is running lean.Any devoted car owner, despite not being a total gear head, must understand and pay attention to his engine’s wellbeing at all times, as many issues can affect this delicate and complicated component.

I had to clean mine out with carburetor cleaner when I replaced the EGR valve. ![]() Did you replace the EGRC-BPT valve? Also, you might swap in the old EGR valve (or a different one from another manufacturer) because I was once sold the wrong part number for my EGR valve.ĭid you check the EGR passageway for clogs? If the EGR valve was functioning improperly, chances are the EGR tubing was carbonized.
