{Chrysler 300} Re: 300B Stumbling at 60+ MPH

[ridgleyracing65 <ridgleyracing65@xxxxxxxxx>]

This has all the indications of a partially plugged exhaust system. How old is the exhaust and mufflers? Car idles and runs great up to the point the exhaust restriction just stops the performance. I have seen this exact same thing before.

Hello Everyone,

Anyone have any suggestions for troubleshooting Carter adjustments (or otherwise) for a car that stumbles beyond 60 mph.  It starts up fine, idles smooth, accelerates strong up to 60 mph and then stumbles...even at fully open throttle.  

I suspect there is an accelerator pump issue or secondary is not opening under vacuum.  Any thoughts/suggestions would be greatly appreciated!

Thanks,

Brian W.
