Well the code only it affects it sometimes, The engine light will be lit up periodically (Sometimes the car will run without ever showing the engine light on, other times it will be on the entire time when it does come on.)
I have noticed a performance hit. It is extremely slow to accelerate when accelerating from a stopped position. It also sometimes won't shift, and will get stuck in a certain gear. So when your just casually driving and press on the gas it will rev much higher than it's supposed to.
On a side note Aaron, How does the WJ do with a drop-in filter from K&N? My filter hasn't been replaced in god knows when lol. So I'm thinking of the K&N since it's re-washable/re-usable instead of a paper filter. Did you notice any improvements from the stock fitler?
