What's up guys. The other day my car started acting a little funny. It's completely stock motor wise, has 184k. First it felt the like throttle response was a little delayed. Kinda bogging. Now it's developed into basically having a rev limiter at 2k rpm.

It doesn't happen all the time but it's the worst in 3rd and 4th gear and under 50%+ throttle. Here's a video: http://youtu.be/PGsqrHKaTUk

I've checked the plugs and wires. Inside the distributor. Changed the fuel filter. Used someone else's MAP sensor, ran it with the map sensor unplugged, and nothing has fixed it.

Does anyone have any ideas at all?
