K&N Intake Help
OK so today I installed a K&N CAI on my 4.6l f150 and I realized that when I Put the truck in Park it almost sounds like it wants to shut off and my revs jump up and down a little bit, they go from 400-500 and the truck starts to make a humming noise coming from the intake i believe. Now when it is in drive the truck feels normal. I also just switched from 89 fuel rating to 87 since it is cheaper and that is what it was our truck where meant to run.

ok before i started to install the CAI I disconnected the battery(only the - side) (is that considered reseting the ecu). I also bought MAF cleaner and cleaned that before installing it into the K&N. The truck starts up fine and then if I put it in Drive it acts normal, but when i put in Park it struggles but then goes to normal.
is that normal?
is that normal?

I had mine struggling after I installed my CAI. It was not until after I did my exhaust system that it went back to normal. With that change my conclusion was that it was bringing in more air than it could handle with the stock exhaust system. Mine was so bad that the engine actually turned off a few times.
