I have been having trouble with car shaking, black smoke, bogging etc etc. Found a thread that states a vacuum hose being loose or popping off the bottom of the map sensor. Now I was looking under my hood and couldnt find anything on the firewall. All I found was the boost sensor. I was just wondering if that is what i am looking for or is a map sensor totally different thing. Sorry if its a dumb question pretty new to fds and so trying to learn whatever i can.

 

Post a pic please

I think it is the map sensor that you found.

Also check out the FAQ for reference to other good threads on the FD:
