Removed K&N CAI, car runs terribly

[dammad]

Since I've been many people advising against the CAI, I decided to remove mine and go back to stock. Unfortunately, when I started it up it ran really badily (spluttering and banging). Tried to give it some gas but that didn't seem to have (just made it worse). Eventually it stalls.

I assume the mixture is wrong. How to get it back to normal? Should I disconnect the battery to get the car back to stock values?

Disconnect the battery - then reconnect it and then it will re-learn it's idle and power curve. It will run rough for the first few minutes while it adjusts the program.

Thanks Loren. Do I need to disconnect it for a while to signal the re-learn? 1 minute? 30 minutes?

Usually 1 minute is enough - 5 minutes is okay too.

Don't forget your radio code and station presets.

Hi Loren.

Would I see the same problem as Dammad if I switch K&N air filter element back to OEM filter?

I think it should not but I like to confirm by a pro :)

Not really a problem - but when you change something that changes the air flow dynamics you should "reset" the DME. This causes it to re-learn the new air flow dynamic and adjust accordingly.
