It could.
Probably a clogged fuel injector or fouled/burned spark plug. Less likely: valve problem.
Vacuum leak, clogged/dirty fuel injector, bad spark plug/ wires.
It means that more than one cylinder has a misfire history. PO301 would be cylinder number 1 misfire. PO302 would be number 3 cylinder misfire.
A misfire in an engine can be caused by various factors such as a faulty spark plug, a clogged fuel injector, a vacuum leak, or a problem with the ignition system. It is important to diagnose the specific issue causing the misfire in order to resolve it effectively.
Usually a bad coil , or plug. if the injector was bad , the computer would have coded for it. But the cylinder 3 coil and plug arent that easy to get to. Its the one at the fire wall
If your plugs, wires, cap, rotor and a compression test check out okay I would suspect the #3 fuel injector.
Spark plug, plug wire, distributor cap, injector, internal engine ........as in a blown head gasket.
a simple cause would be if distributor equiped carbon trace on the distributor cap,bad contact point,bad ignition wire(spark plug wire) if direct ignition then it could be a bad coil. another reason a clogged injector.,low compression.
I would make sure power is getting to the fuel injector use a noid light to test it. You may also want to check the fuel pressure also the intake manifold may have a leak that can cause a misfire as well. Glad your compression is good. That is a sure sign its something simple.
Check the spark plug and the plug wire. If that isn't the problem then check compression. You could also have a bad fuel injector.
I would check your spark plug first, then I would go to the injector. This happend to me and it was the injector.
