Where is map sensor? (pic please) What other sensor could cause erratic boost and extreme shaking. It almost sounds like its running on one rotor like those cruiser motorcycles sound...

I understand it might be engine failure, but I never could find the map sensor that people asked me to check. Is it the one closest to firewall and highest mounted. Is the map senor the same as the boost sensor?

Say it was a broken seal or some case that required a rebuild, would it be ok to try and start it?

Other symptomes(sp?): The car would not idle with the cat connected. I took it off and it idle on it own just really really weird. One of the motor mount were broken so the engine would shake extremely. Now it been sitting in my garage for the last to months.

Another question: Is it ok for the car to sit like that. I know the battary will die but will there be any other problems that might hurt the car...

Thanks guys for all you help!!!

 

 

Yes

 

Well thats not disconnected. How about the other questions? THanks....

 

Did you check it under the intake manifold also? It can be disconnected under there also.
