The problem with running on only 3 cylinders isn't the unbalanced load on the crank. The problem is all the unburnt fuel from the dead cylinder will end up burning off in the turbo and catalytic converter. This can kill those parts.

A worn out or faulty spark plug is a leading cause why your car engine vibrates or shakes uncontrollably. A worn out spark plug can prevent the fuel-air mixture to not get properly ignited in the cylinders, thus leading to misfiring. ... Installing new spark plugs is the best way to resolve such vibration related issues.

Driving with a misfire isn't safe and can damage your engine. The cylinder is the part of the engine where combustion takes place. ... A misfiring cylinder can cause a proportional loss of power. For example, if one cylinder misfires in a four-cylinder engine, the car will lose 25 percent of its power.

As dieselss mentioned, if oil is low it will not allow coil to spark. If oil level is good, disconnect yellow wire going to low oil sensor mounted near on/off switch. If it starts with wire disconnected, then the sensor is bad. You can run with sensor disconnected but replace ASAP!

A bad spark plug may cause your engine to sound rough while idling. The vehicle-encompassing, jittery sound will also cause your vehicle to vibrate. It can indicate a spark plug problem in which a cylinder misfires only while idle.

The P0171 code means that, on the first bank of the engine, the fuel system is running weak or a vacuum leak exists near this side of the engine. A lean condition occurs when the engine either receives too little fuel or too much air.

If backfiring into the exhaust it could be a valve problem or timing problem, either ignition or cam! A leaking, bent or sticking valve allows mixture to be pushed into the manifolds on the compression stroke, then ignited.

A DPFE will not cause the car to misfire. It is either a DIS, Coil pack, wires or plugs.

Too much air flowing into the intake causes the engine to lean out [too much air in relation to the fuel] and misfire. At an idle, the PCV valve restricts air flow, to reduce this problem. At high manifold vacuum [idle], a spring loaded valve is drawn up and partially restricts flow to the crankcase.

A weak pump that isn't delivering adequate pressure can cause an engine to run lean, misfire and hesitate when accelerating. ... The pump might be getting wear, a clogged fuel filter might be restricting fuel flow to the engine, or the pump might not be getting enough volts through its power circuit to run at normal speed.

Most overheating issues related to air/fuel ratios are the result of a lean mixture, which causes the cylinders to run hotter. ... Considering the principles of ignition timing, if the spark occurs to soon or too late, the cylinders will run too hot and the engine can suffer from power loss.

If the fluid is full of bubbles or is foamy, the transmission is probably overfilled with ATF. Other causes include using the wrong type of ATF or a plugged transmission vent.

Engine misfires, rough idle, and loss of power One of the most common symptoms associated with a faulty ignition coil is engine performance issues. As the ignition coils are among the ignition system's most vital components, an issue can cause spark to be compromised, which can quickly lead to performance issues.
