Sorry, I could find any help with chrysler, I thought Dodge and Chrysler have similar engine. I need help, my Chrysler 97 TownandCountry, 3.8, always misfiring when the engine hot, first gave me faulty camshaft sensor and misfiring code using ODBII. Replaced camshaft and crankshaft sensor, now only misfiring code occurs but the misfiring still happen. Took it to Dealer and stayed over a week, they said it's wiring harness by the traniny had a hole causing a close contact w/ ground, they put a patch, but problem still occurs. I took it back to Dealer, they still could not find what causing the misfiring after another week at the shop, reason: the techinician too busy working on other cars, very dissaponting. Bad experience at Cerritos Chrysler in Los Angeles. I had BOSCH platinum spark plugs replaced beforehand, could this the problem too? when it's cold engine is running smooth. Pls. help...thanks

 

It could be your coil. when it get's hot the primary wiring and the secondary are expanded and causing a miss fire. I had this happen on a old 318 once.
