Huh. I did it on mine and within the 1st hour she threw a check engine light. Threw a lean code and a rich code! Mine did not like it at all, was running rough also. I put it back to stock and it's running normal again.
I opened it up completely, full throttle. And at some point after that, the light came on, then, it would idle rough for a few seconds upon startup. It would even out pretty quickly, but acceleration was definitely diminished. The code wouldn't clear either. After I put it back to stock, it still wouldn't clear. I did notice the acceleration was back right away. I drove it for a few days stock with the light on. Then yesterday, I opened her all the way up again and I noticed the light was off a short time later. I didn't actually see the light come on or go off. I'm merely speculating on the causes.
That's crazy me and two other people did the same exact set up and no one ran into an issue like that. Those other guys have intakes now with the same hose deleted and they don't have any issues.This one's definitely a head scratcher.
For sure. What intakes are they running? The Forte 1.6? If so, how did they reuse or bypass the mass air flow sensor? I've been on the fence about going that direction, but after these issues. I think I'll wait. I also have a pedal commander installed. Which changes the frequency of your electronic throttle to give you more throttle response. Maybe that is contributing to my issues....
The filter goes on the intake end, so that unfiltered air doesn't go into your engine. The hose is removed completely. The other end of the house goes to the diverter (blow off) valve. Since it's only pushing air out (in theory) doesn't need to have a filter
