Hey I just got a K&N AirCharger CAI installed on my 2005 2.0l focus. now heres the problem... i got my car back and drove it to see how it worked. so i toke off and got to about 60 mph and then slowed down and as i approached the stop light, with my RPMs dieing down to about 1000, the RPMs dramatically drop to about 200 and stalled out. So i drove it around some more and it seemed some what fine... but the RPMs were still bouncing around, which isnt normal for my car. and since ive been driving it, its happened about 8 times more. it doesnt do it everytime i slow down, it tends to do it more at the start of the car being on but its mostly random. Does anyone have any suggestions for me? Is there maybe a problem with one of the air sensors and i either plugged it when i wasnt supposed to or i left one off? THANKS!
