2018 Chrysler 300 Hard Start

Without a scope this car wouldn't be fixed. Guys if you don't have a scope as part of your daily diagnosing tool aresenal you are falling behind. The ATS Escope is a scope that will put you on the fast track to a successful repair. Bernie..as always thank you for showing us your diagnostic game plan. Data driven diagnostics is a sure fire way to a quick and proper repair!

Thanks Bernie, excellent presentation! Nice to be able to see it thru to the end.

That was cool Bernie. Thanks for the lesson. No question that a good scope and qualified operator can find the strangest problems. Nice work.

Thanks Bernie, well done!

Great case study. We had a Toyota once with a bent tooth.

thanks Bernie , your scope is awesome , but more important , your knowledge is oustanding that make this kind of diagnostic so simple , thank you very much to keep posting these awesome videos.

Is it just me, or does it almost look like every tooth has witness marks along the outer edge? Maybe it's the lighting of the camera with the borescope but it almost looks like they all hit something at least briefly. I'm wondering if maybe the vehicle did need a CKP initially. Aftermarket part is installed that is too long that bends one tooth and briefly contacts all the other teeth before it…

Phil The sensor that was in the engine was cut off and pounded into the engine. The CKP sensor, or at least part of it was in the oil pan when the shop removed it. So when it was pounded into the engine it bent the tooth.

That makes sense. Thanks for the additional information.

And the collective at DN sighs in exasperation. I hope the shop ate all of the extra expenses for their screwup.
