2.Loss of Power
Most gas-powered vehicles are designed with an internal combustion engine. These car engines use a four-stroke combustion cycle to convert gasoline into the power needed to make your vehicle move. The four strokes are the intake stroke, compression stroke, combustion stroke and exhaust stroke. The loss of power you are experiencing could be stemming from a hiccup from any one of these four steps (strokes) in the combustion process.
3.Gas Mileage Drop-off
If you notice the distance your gas tank takes you is not what it used to me, it could be an indication that there is an issue in the compression stroke of your engine. In this instance, using a fuel cleaner, or having a fuel system service performed, may clear up the issue. Depending on how long it has been, it might be worth considering a tune-up. If these two recommendations do not help the gas mileage front, having an engine diagnostic performed might provide you with the information and options you are looking for to correct the issue.
Knocking, backfiring, hissing, spitting and popping are all sounds we do not want to hear when we start our vehicles. These noises can occur when there is an abnormality in the combustion flow. If you are hearing engine knocking, popping, spitting or your vehicle backfires, have it serviced ASAP.
Many of us who has learned to drive on a manual transmission understand the nature of an engine stall. For those who are unfamiliar, when the clutch pedal and gas pedal are not engaged at the right speed, your car will stop and require a restart - a most frustrating and embarrassing event - especially in traffic.
When the exhaust stroke of your internal combustion engine is starting to fail, it could give off a noxious odor from the exhaust. Much like the familiar sounds of imminent failure, this odor is a tip-off that your vehicle needs attention from a professional.
7.Engine Continues to Run after Ignition is Turned Off
This occurrence, also known as run-on and dieseling, is most common with high-performance vehicles and usually happens when the octane in the gas is incorrect. Other culprits could be a failing solenoid or an over-active carburetor. If this is happening with your vehicle, your local Speed Shop will have the answers you need to get your vehicle back to maximum performance.
8.Rough Running Engine
If your engine is running or idling rough the fix might be as simple as a tune-up. The most common cause of a rough running engine is clogs in the system or old spark plugs. Other issues could be an incorrect octane in the gasoline or a low battery
