fuel pump priming ? make sure the filter isnt hanging off the CAI...sounds like the same problem i use to have, until i found out there was a hole rubbed into my shitty first cold air intake, so i got the Injen as well...

first off all the codes would consist of a misfire, p0300 is a random misfire, p0171 is a lean code, and p0326 is a knock sensor issue, prob from the misfire, you are detonating, so you prob got bad gas. get you some sea foam, put it into the tank, get you some 93 from like shell or bp. and run it without getting on it, then go for a ride but before you do this disconnect the power wire from the batter and negative, touch them together for a sec and let the car sit for 10 min, then put it all back together then go see if t goes away.

i always run shell 93 and i just cleaned the maf sensor and it still is doing it... this is what idle sounds like

take your throttle body off and clean it. Also check for a vacuum leak. you either have bad gas which is causing your issue, 2 your maf got somthing on it even tho you cleaned it it is still there, 3 your tune is far off, 4 your o2 sensor is screwed, check for the wire to make sre its not grounded ouyt on the exaust manifold.

Lean code,got to have a leak somewhere .check the cai where it passes by the rad support.

Check vacuum hoses etc.
