The Car Stalls Out And DiesSuppose your engine turns over and your car starts, but it stalls shortly thereafter. This type of situation suggests the ignition system is fine. However, something may be wrong with the fuel. The problem may involve the fuel pump, water heavy gasoline, or a failing relay.Engine Hesitates When AcceleratingThere are many factors that might contribute to hesitation while accelerating. For example, a failing fuel pump can play a role as can a clogged catalytic converter.

The manifold absolute pressure (MAP) sensor may be faulty or the exhaust gas recirculation (EGR) system might be defective. There may also be a vacuum leak impacting compression.Another problem similar to hesitation is an overall lack of power under load. For instance, while pulling something heavy up a steep incline, it might seem as if your vehicle is running out of gasoline.

The potential causes of this issue are the same as those which cause hesitation: obstructed catalytic converter, failing fuel pump, EGR problems, etc.Misfiring Under LoadIf your vehicle begins to misfire when accelerating, the issue will usually involve a vacuum leak. Fortunately, vacuum leaks Color Coated Steel Coil Suppliers can often be resolved easily by replacing hoses that have become worn and begun to deteriorate.

The challenge is finding the location of the leak.There are also many other potential causes for a misfire under load. A clogged fuel injector, bad spark plugs, failing ignition coil, and a weak fuel pump can each contribute to the problem.Temperature Related Drivability IssuesIf you notice your vehicle experiences problems only when the temperature is hot, the issue may involve a shorting circuit board.
