CAI causing issues...
Got a lovely 2010 SES a few months ago and it's such a beauty that I wanted to start modifying it. Anyways I got a K&N 69 Typhoon CAI (the one their website says is for the 2010 SES) and install went great. Car sounded great, felt a little more pick up, no problems.
That was a week and a half ago, then a few days ago at around 1500 rpm it seems to judder and won't switch overinto higher gear (automatic) unless I floor it and let the overdrive kick in and it still doesn't sound quite right.
What do you think, is this a transmission problem that just cropped up at the same time or is the CAI messing with stuff? I haven't gotten a flasher yet, was gonna wait til I installed the exhuast.
I did call K&N and the lady I talked to seemed to think I got the wrong CAI, that because I had a TiVCT engine K&N didn't have one. Now I know I am knew to this, but I'm pretty damn sure I have a normal Duratec 2.0L.
