2006 Dodge Caravan
Engine size = 3.3L V6
Warning lights: Check engine light on and off.
Repairs for this problem: Fuel injector cleaner.
Question: What causes bucking at about 45.

Answer: When the check engine light is on, the computer has seen something in the emissions system or your Dodge that is not functioning properly. If the the engine is bucking whn accelerating from 45 MPH as to make a pass, this may be a problem in the ignition system. Acceleration at a higher speed puts a heavy load on the ignition. Most common is faulty spark plug or spark plug wire. A scan of the computer for stored trouble codes may indicate which cylinder has the problem. A code like P0300 or P030X, where X is the cylinder number. If you are at a steady speed and the bucking seems to come and go, this could be a transmission problem in your Caravan. Again, computer codes are the key. I would start by looking at the ignition. If the engine light is flashing, this mean that it is definitely an engine misfire, and is bad enough to cause catalytic converter damage. That's what the flashing means. It is more serious and needs to be looked at as soon as possible.

    Does My Car Need A Front End Alignment?

    Why should you get a front end alignment? Improper front end alignment is a major cause of premature tire wear. Over years of driving, a properly aligned vehicle can add thousands of miles to the life of your tires. Most tires are replaced because of premature wear caused by the front end being out of alignment. When the front end is line properly, this makes it easier for the car to roll. Read more...
