I have a 2006 Dodge Caravan-had a tune up 5 months ago, the engine is now misfiring and my mechanic is having a hard time diagnosing the problem. Please email me at [email protected] if you have any suggestions/solutions for me... Thanks!

Ensure that you only installed the same Champion Spark Plugs that came in the vehicle--no cross-reference plugs. I've seen disasters by installing non-Champion plugs in Chrysler products.
