Slight stumble when idling
 

Hi, I’m new here. I have a 2011 T&C with 99,000 miles.
I see the recommended mileage to change the spark plug is 96,000 miles. I have 99,000. .it sounds like a pita to change the plugs, pull the intake manifold? Really? Maybe I’m just old school.
The car seems to run fine it’s just at idle I can perceive a slight stumble, slightly rough patch. There are no CEL’s and it has sat a bit for the last few weeks, maybe a month. Could it just be old gas?
thank you,
Chris

YUP, a bit of a PITA...BUT SHOULD be done! At that mileage and having sat for a month(maybe more???), a good fuel injection system additive like Sea Foam in the tank will certainly help clean up the fuel injectors and carbon build up in the cylinders.
