about a week ago my car started hesitating at around 3,500 RPMs and higher. The car would even get a little jerky. I took off my intake only to notice oil sitting in my midpipe. The oil was coming from the PVC hose(the one connecting the engine to the intake) I would assume this is causing the jerkiness. Oil being sucked into the intake runners. Has anyone else had this problem? How can I fix it? Is it dangerous to drive the car?

Thanks.

Oil coming in through the PCV line is common in any car. I don't have an aftermarket intake (yet!) but the stocker has a rectangular oil trap that these PCV lines run into, so you never see the oil. From the description of the problems you're having, it sounds more like a vacuum leak. If you can't find anything obvious, substitute the stock intake back in and see if the problem goes away. Probably a wise idea to repalce the PCV too.

I will check for a leak, but it is always jerky. I know that is not normal.

I will try the PCV valve. I have never changed it and the car has 51.000 miles. I'm guessing that the previous owner never did either. (bought with 33,000 miles)
