Re: I want to learn about cars
Anything lost during the four cycles could cause a misfire:
Air - Bad air filter, bad MAF sensor,Bad HO2 sensors, dirty throttle body, unmetered air leaks in PCV, EGR, and air Intake system.
Fuel - Bad fuel filter, bad fuel pump, fuel pump fuse, relay, or injector.
Compression - Bad Intake/Exhaust valves, or rings.
Ignition timing - Bad spark plug, wire, COP, Coil, ignition module, or bad physical timing.
Exhaust - Bad or broken catalytic converters are are known to block the exhaust flow and choke an engine out.
Questions can point us in the right direction.
Is the Check Engine Light (CEL) on?
Do you know the Diagnostic Trouble Code (DTC) ?
Is the misfire on a single cylinder, or random misfires on random cylinders?
Doe's bad weather, or car wash play a factor?
How old/mileage ?
Is your car maintenance on schedule?
