Hi to all and I'm the new guy.....Been having warm hard start problems with my 1995 E250 for about 2 years now, and a little bit ago found on a forum here the reason. It is apparently the air charge temperature sensor. Does anyone have a clue where this sensor is located? Thank you!!!

 

Depends on what engine you have, but on the 5.0 and the 5.8 it is located behind the thermostat housing in the intake manifold near the plenum. It looks like the coolant temp sensor but is a 2 wire sensor and is in the intake plumbing.

 

My van has the 4.9 straight six
