cylinders 3 and 6 are not, "firing properly."90% sure its either those 2 spark pluggs or those 2 spark plug wires.Replace them and if you fixed it the light will go off as long as theres n other codes...(problems).pluggs are cheaper to fix.and u can tell by sight if yheyre good or noyt.Sp Id start there.
If you have a "check engine" light on, start with having the codes read. A misfire code can tell you which cylinder or cylinders are having problems. A misfire could be the cause of your engine vibration.
The year, make and engine info would help us help you.
sounds like you need to replace points ,or rotar button or distributor cap in engine
It can as one or more cylinders may have a misfire. A blown head gasket will destroy your engine.
what are the possible causes of misfire on number one cylinder in a dodge 2003 ram 4.7 liter engine
Terrorists
An intermittent crankshaft sensor will not let the engine fire the correct times. This can definitely cause a misfire for the engine.
Do a proper diagnosis to figure out the cause of the misfire, then repair it.
It means the computer is detecting a misfire on those cylinders, the most common cause is worn spark plugs or spark plug wires. I would recomend replaces both then clear the computer codes and see if the service engine light comes back on.
Yes
ignition coil
An engine computer does not cause a misfire but merely reports it. The misfire is probably caused by the ignition coil or plug wires
