So my car was running just fine till I decided to mess with it and then murphy's law kicked me in the nuts, I got a k&n that bolts right up to the maf sensor and that is the only change I did I didnt switch mafs or anything and now my car wont idle it just surges and then dies, but then sometimes it will run fine and idle normal, then I heard that u need like 9 inches before ur maf so it just not random air flowing in and throw everything off, I have no freaking clue what the crap to do and I dont have my old intake anymore so do u think putting a velocity stack inside the K&N would help regulate air flow because I went from a really tiny air filter to a pretty stinking big one and I wish I had my camera to take a picture but dont know where it is. Anyone know what I should do?
