I replaced the spark plugs in my wife's 02 T&C(3.8) at 125K with Bosch+4 plugs, now at 130K is getting a hard cold start problems, in the morning after being parked all night it takes longer to start(just a little more cranking time) than when it is already warmed up, no codes no MIL on, no other problems(knock on wood).

So I'm thinking of going back to champion plugs, should I??? or what should I do??

 

Absolutely.....................

Chrysler Ignition systems are VERY PICKY about what you use for spark plugs.....

This is Classic..... The correct champion Plugs will fix you right up...

 

yes champion only
