How to Deal with Misfires in Your Chevrolet Colorado
The combustion process requires a specific timing from the intake valve, exhaust valve, piston, and the spark plug. Correct timing allows for the spark plug to fire when it is supposed to. In turn, the heat produced in the chamber is converted by the pistons, connecting rods, and crankshaft into mechanical power. However, if firing happens at the wrong time, the burnt fuel will just be trashed, and the energy that\'s supposed to power the vehicle shall be lost. How would you know if your Chevrolet Colorado is suffering from engine misfires, and how should you deal with the problem?
When your vehicle starts to run slow
When the engine misfires, a significant amount of power is lost. When the occurrence of the problem continues, expect the vehicle to start running slower and more sluggish. And before you know it your engine is already nearing the end of its life. But you can still save your engine from reaching its breaking point by giving the necessary solution for each possible cause of misfires.
When misfires choose to trouble you at all speeds
Problem with the ignition system is a common reason why misfires occur at all speeds. A faulty ignition system prevents correct ignition timing, because it may already be needing replacement. It is wise to have every function checked by a well-equipped shop in order for the timing to be set according to the marker\'s specifications on the emission-control decal. But if you notice that it\'s simply due wet ignition, you\'ll just have to dry them. You may need to also check the spark plugs because they may actually be causing the misfires. If problem is still not resolved, the carburetor or the fuel injection system would need attention as well.
A faulty fuel system can also cause misfires, because it may not be able to provide the needed fuel right when the intake valve opens for power generation. Check its fuel filter for clogs, a bad pump, and ice in the fuel line. If there is dirt or water in the gas, you\'ll have to drain the fuel, and clean the lines before you do the refill. Misfires also occur during warm weather, when vapor lock happens, and cooling it is the simple solution. For a heat control valve that is stuck, free it using a choke cleaner. Also check vacuum hose as well as the evaporative emission control system. But if everything fails to cure the problem, you may need an engine repair because of low compression.
When misfires hold you from reaching high speeds
Aside from the possible misfire causes already mentioned, the choke plate can also cause misfires when it is stuck or incorrectly set. You will need to manually close the choke, reset it, or just have the linkage cleaned or adjusted. Also check the grade of gasoline, and adjust as necessary. If the air cleaner is already clogged, replace it. If the weather is damp, carburetor icing could be the real problem, with which adding isopropyl alcohol is the solution. For worn or broken internal engine parts though, repair could be your last resort.
