Put a caravan 2007 3.3 in a 2003 caravan. Drove great for 5 mins then died. Won't start, smells like gas, code p0106. help

SOURCE: Caravan runs very rough at start up when cold

have you installed new plugs lately,if so have someone check the Engine Coolant Switch,
this sensor tells the engine how cold it is so the computer knows what kind of fuel mixture it will need.
rich or lean

SOURCE: running problems

Idle air control valve or a vacuum leak, the idle air control valve controls the amount of air let into your engine when you start or while running you holding your foot on the gas lets more air in.

SOURCE: p0106 and p0107 codes are coming up on 2001 dodge

have you checked the egr system and check for a vacuum leak???

SOURCE: 200 grand caravan 3.3. Ran

Have you checked to see if all of the fuses are good? That could be the cause for the radio and the tripometer not working.
