I have a 2015 3.8 not r spec or ultimate.
I’ve been having issues w my car the car when coming to a stop and no other time I will be rolling to a stop in N and my ride will be normal then all of a sudden mygas consumption gadge will go to 16 and my rpm will slowly climb and then I stop and it will go to 0 and my car will sound like it Boggs out (does not stall just don’t sound good ) I don’t think there’s any knock or anything but today it was the worst it’s been usally it’s just going up to maybe 1500-1800 rpm MAX TODAY HIT DID IT TO 3k please help thinking maybe throttle body issue or even maybe a fuel issue pump or stuck injector plz help!!!!!!
So far so good. I haven't noticed the mpg and torque numbers rising after cleaning that, so it must have done the trick! Thanks....would a dirty air filter possibly cause that as well? Looks like mine does need to be replaced lol
