After all that talk of sensors and how they can help your car, it only seems fitting to start with how failed sensor can actually harm it! Look at the following with your scantool (as shown in Figure 7): throttle position, mass airflow (MAF), short term fuel trim (STFT), long term fuel trim (LTFT), ignition timing, and fuel pressure (if a PID is available). Steady low between 5-10″hg vacuum: This indicates that the engine has a leak in the intake manifold or the intake gasket. If you have any Prevent stalling problems before they start with a tune-up kit. is they need to be right or you will just keep paying until they stumble across If you have car engine compression problems, your car will either misfire when you start the engine, perform poorly or, if you have low or no compression in all cylinders, won’t start at all. the problem if they have misdiagnosed the difficulty. If we were to talk about a specific and very popular engine, the Cummins 370 Diamond, IMO, AN ACCURATE 3100 RPM loaded for bear is the minimum you should see, but we prefer 3125-3150. I am going to stress that again. However there are several common problems that can develop over time. Also understand that on many planing hulls, during the acceleration mode from 9-15K or so (getting over the “HUMP”), some, to more than “some”, black smoke could be perfectly normal as the engine pulls close to its maximum torque during the 10-60+ seconds it may take to get the vessel up on top. Low fuel pressure: Most fuel supply issues originate from insufficient pressure. Now it’s today and we have the same engine and we are at the 3200 RPM with the same props turning at the same 1600 RPM, but the boat is only traveling at 19-20K’s.. Hmmmmmm ??? easily done on most cars and is part of a regular maintenance schedule as well. How engine loading and propellers interact with vessel performance Photo credit: James & Jennifer Hamilton mvdirona.com. This kind of problem will usually not turn on the check engine light. Other problems that cause acceleration stumble include vacuum leaks, low fuel pressure, a weak spark caused by low coil voltage or bad coil(s), retarded ignition timing, and contaminated gas. taps designed for testing. Check the turbocharger while the engine is running. Chances are the gaskets have become hardened beyond their ability to seal the engine. Installed a clear line with a loop in it just before the engine in case you think you have an air leak?? But in reality, it is actually much easier. In this guide, you will learn about common problems that cause BMW engine malfunction and how to diagnose the problem yourself. The engines are just turning them at the same RPM. Regardless of why, being overloaded is directly related to the propeller matching the vessels current running configuration, weight, vessel bottom condition, windage, or running gear issues/conditions, but all of these go back to the prop as they all make the engine work harder because of these conditions, and slow the vessel down overloading the engine. It's not quite a stutter, not quite a stall, and it doesn't matter if the engine is hot, cold, or low on gas. The problem may occur when the engine is hot or cold or when you are low on fuel. There are some instances when more serious consequences like engine seizure or even vehicle fires result from problems with reduced power. Engine Stalling, Surging or Running Rough. As these clutches wear they fail to transmit the instance a dirty air filter will cost you between $20.00 and $35.00 (US). causing the low power issue. The fuel the engine goes "out of time" but will still run with the result being low A faulty fuel injector will cause your engine to misfire, and these can be pretty difficult to diagnose without flow testing them. Again, remember it’s the props that make the boat move forward, the engine is only turning them. When Solution: EGR valve. Although a vacuum gauge is much easier to install, it does not always tell the whole story. The Answer: It’s not a fuel supply issue (clogged filters, air leaks, etc, etc). Internal mechanical failures can cause an engine to not produce We’ve been serving local Ventura County, California since 1980 as a custom boat builder, repower specialist, designer, and supplier of equipment to builders, commercial fishermen, and recreational users.
