p0303 question

yesterday my car threw the code p0303 for cylinder 3 misfire however i cant notice its misfiring....i was wondering if anyone know the solution for this...im assuming plugs and wires but im not entirely sure and would this cause a hesitation at high rpm with full boost on shifting? almost feels like a fuel cut

The LNF does not have a serviceable fuel filter.

But yeah, as stated before, plugs are definitely the first place to look. Could also be a boost leak, O2 sensor, Map sensor, Maf sensor.. etc

mine randomly flashed this morning and it was a p0303 code. When the check engine light was flashing, my car was bogging out and turbo fluttering, then the light went off and then the car had regular power again, and this was all around 50% throttle..my car has been fluttering and bogging out randomly for a while now without any codes, so maybe i have a boost leak thats causing misfires????

Ok.. well.. I don't wanna be a dick, but haven't a bunch of ppl already told you this in your other thread? :P Did you test it yet? /sigh I'm no expert, but when there's 4 pages of guys all basically saying the same damn thing, I'd say at least check it out!
