I have a 2005 Chrysler 300C ( original owner )
Mileage 172,000 and I take care of my car. I use full synthetic oil and change it every 5000 miles.
I noticed a hesitation between 1000 and 2000 RPM’s. It disappears after 2000 RPM’s.
TheChrysler dealer kept doing repairs and claimed the problem was gone and it is still there. The dealer did a full tune up, induction service and also replaced the EGR valve, gasket and seal. Nothing has helped. The problem gets worse in higher mountain altitudes.
Can anyone help?
