Engine tic caused by Air charger

Hey TW, I was wondering if anyone could help me out. I installed a K and N air charger the 63 series. Shortly there after I developed an engine tic. I read all the threads I could and I did the "washer fix" however the tic persisted. I reinstalled the factory set up and the tic has vanished. I am pretty certain that every single hose was sealed and I didn't receive any engine warning lights. Has anyone else dealt with this or did I some how make a stupid mistake. Thanks for any input.

 

the mistake was the K&N. Be happy with stock, urd or afe.

 

Yeah I am seeing that now, back home we used to swear by K and N. WTF happened

 

K and N have always sucked.... yeah you might make 2 more hp but they filter like crap. Stick with stock.

 

Good advertising now but back in the day combustion wasnt so controlled with computers. Now you can have a dirty airfilter and it wont matter much.
