I have a 98 neon 2.0 sohc that stars fine but when it idles down (right after starting) it tries to die. If you feather the gas peddle you can get it to idle but rough. It seems to rev up ok but when you let off the gas peddle it tries to die does not matter if its worm or cold you get the same reaction. It through code po108 which says Manifold absolute pressure high. My all data shows it to be map sensor voltage too high. Any help would be greatly appreciated.

Thank you.

 

I think its the MAP sensor.

 

Yup it was the MAP sensor.
