It a 2008 ram ..5.7 HDMI auto..

Could the map sensor cause my troubles? It went into limp mode again Thursday. I unconnected and reconnect plugs on the truck also cleaned the grounds on it too.. It running OK I really need someone to look it over and give me ideas to look for...

The parts I have replaced so far!
Throttle body
Crank sensor (twice)
Cam sensor
Coolant sensor I thought it was leaking.

I'm unemployed just looking for more info on this truck!
