Servicing Chrysler’s Versatile 3.3L And 3.8L Engines
These engines have a mixed reputation for being high-mileage, dependable powerplants as well as noisy motors that can fail at relatively low mileage. Some 3.3/3.8L V6s have racked up well over 200,000-plus miles on the odometer with no major problems (except some oil burning), while others have called it quits at 70,000 to 80,000 miles.
Diagnosing Rough Idle On Chrysler 2003 Town & Country
According to the owner, the 3.8L Town & Country had been driven for quite awhile with an illuminated Check Engine light and a rough idle condition. As the vehicle was driven, the idle condition worsened until the engine wouldn’t idle in gear unless the driver applied the throttle. Of course, the vehicle owner had assumed that the rough idle complaint was caused by only one component failure and would therefore be relatively simple to repair.
