2007 300C stalls/hesitates/cuts-out
 

My 2007 Chrysler 300C stalls/hesitates/cuts-out when I am driving at speeds between 40 and 60 MPH. I've just had a major tune-up to include new coils and new plugs. The car still accelerates to high speed very well. I had it checked and there are no codes in the system at all.

Can anyone give me any ideas about what might be the problem. Any comments/ideas will be appreciated. Thanks.

You need to get some codes. Go to AutoZone or AdvanceAuto and they will read any code stored in your car's diagnostic system. Sometimes it takes awhile for enough info to be collected to register a code.

Have you taken it back to the shop that did the tune up? It could be something not connected up properly.

Tarhealcracker,
Thanks for your suggestion. I'm going to take it back to the Chrysler dealer to have them look for codes again.
