Check Engine Light Error Code P0300 multiple cylinder misfire. Just installed a Fast Intentions LTH then after driving for few miles this error camed out. Other mods CAI and CBE but i have this mods before already and the error code didn't appear only now after the LTH install. Need help on how to resolve this thank you.

First thing I'd check is if the exhaust manifold or piping is hitting something. If that's not it, you may need a tune. FSM may have some clues.

i had that code, replaced the spark plugs and got silicon breather hoses for the CAI and it went away.

I've been having the same issue since I bought my Nismo. Dealership has changed the Gas, the oil, did a compression test, a leak down test. It still happens. It will be looked at by a Nissan Engineer on Monday. I'll let you know what they say.
