The Headgaskets where just changed so the motor was torn all apart and now that it is back together the motor sputters when turning it on and acts like it wants to die but once you get it started and the motor warms up you can shut it off and turn it back on with no problems and the car runs perfectly.. I used the obd II on it and i get a error like manifold absolute pressure/ Denso sensor... Can anyone help me with this??? I am not sure if this could be caused by a sensor and if so what sensor may this be?
 
MAP sensor is what tells the computer how to adjust your fuel. It is run by a vacuum off of the intake manifold, usually. Also, locate your idle air control valve and throttle body and clean these to showroom new condition. Use Gum-out spray. Also, you might want to replace the engine temperature sensor as a matter of course. This sensor tells the computer how to adjust the fuel based on engine temperature. If the head were removed, they might have forgotten to re-connect a few switches. Good Luck!!
