I installed the K&N FIPK kit yesterday and no install problems. Now there is this popping noise coming from the intake. It was there before the intake but not as noticable.

I cleaned the MAF and sprayed some throttle body cleaner in, and that didnt fix it. Im going to clean the IAC today and see if that helps.

I talked to a friend and he said that it could be running rich???

Any ideas????

The only other mods it has is a throttle body spacer, and a super 44 with stock pipes.

 

Pre-ignition or really lean condition

 

by popping noise . do you mean metalic, backfire or something else
