Hi everybody.
I have a VW Routan(Crysler Town&Country) 2009 4.0, bought it used at 109000 miles so don't know its history.
It cranks and starts fine, engine runs smooth but has the following issues: bad gas mileage(14-15 mpg average), shudders when cruising at low speeds of 40-50 mph, and the engine stalled at idle on 3 occasions. Was told that could be spark plugs going bad or clogged intake manifold. Any ideas? Thanks in advance

 

what if any are the codes in the computer?

 

No check engine light, no codes
