It ran fine yesterday. I hadn't really driven my car hard other than 110 down the freeway and 90 or so down the roads by my house night before it broke. Anyways, I get up for school and turn it on. Starts shaking really bad, settles out a bit but it's still not right.
I back out thinking it's just comming out of the cold from sitting for about 20 hours. Drive it up the street and the engine light comes on so I park it back in the garrage.
Get back home and take a look at it. Friend thinks it could be a vaccum leak or collapsed cat. Wasn't sure how to check for that without having codes pulled. Anyways, I thought about the cat. and checked the exhaust. Two tips, one blowing air .. and the other alternating in and out with air. In rythm with the engine cycles.
No idea what that means except that something is wrong in just one, possibly two cylinders being as only one tip is acting up like that.
