Check vacuum lines around an engine.
Tell me what code you are getting .
A barometric pressure sensor dose not work on its own .
You have the mass air flow sensor this is the first air sensor coming into the vehicle then you have an air temp sensor then what is called ECT engine coolant temp sensor .
The problem to me sounds like the MAP sensor manifold absolute pressure .You loss this the vehicle is not going to run to good.
If it wore the mass air flow it would cost the most the map is far less in price still not cheap the barometric sensor it likely a symptom of the real problem .
Check the gas flow in side the engine like EGR and EVAP systems to a vacuum thing .

Its located in the air filter housing....The volume air flow sensor also incorporates the barometric pressure sensor and the air intake sensor....If you are replacing either of these sensors replace the volume airflow sensor.......

the correct transmission fluid is ATF+4, any other trans fluid will spoil the transmission.
i use platinum spark plugs in my engine, works great.

Hey have you tried disconnecting and re connecting the battery? my mitsi carisma startd doing that so i rang up dealer and aparently they do it when the computer thinks there is something wrong with the engine, so it enters slow mode (or turtle mode or something) so that minimal damage is done while you drive it slowly to yr mechanic. Could be complettly wrong tho. Good luck.
