It sounds like fuel injectors are clogged.Who ever scans it again, have
them check the adaptive memory for fuel cells. If any are reading over 10,
you got clogged injectors.This is a common problem on the 2.5 when you buy
cheap off brand gas because of the small opening in the injector
nozzle.They can be cleaned by hooking a machine to fuel rail and running
special cleaner thru it.Cost is about $75.00-$100.00
