Hey all I've posted a couple times about this already but I'm hoping I can get more responses. I have the above codes, have had them for a week or so. Car intermittently stalls at red lights, rough idle. Today the check engine light started to flash as soon as I got home. I started it back up and the light stayed on, but I have to bring it somewhere tomorrow to get looked at. I was thinking the crankshaft position sensor or o2 sensor to start. I have changed the spark plugs 2x as well as the ESIM valve, oil and filter change, ran additives all to no avail. There is also a drip coming out of the exhaust at the connection to the muffler would this be the cause? Sorry for the essay you guys are very informative and I hope to gain more insight on the issue. Thanks all

Correct that's what you pull out to access the spark plug.

Also would a bad 02 sensor be responsible for the engine stalls and misfires?? If so, any luck with non-mopar sensors? I see new on rock auto Bosch for 20
Absolutely could but the misfire will be dumping raw fuel to the exhaust and throwing air/fuel readings out of whack. If you want to replace it anyway it can't hurt but go with a Mopar or NTK sensor. Bosch don't seem to play well with Chrysler products.

easy way to check coil packs...although not really recommended....is to slightly pull one off at a time....you certainly risk being shocked doing it that way though. If you pull one off...and it DOES NOT change how the engine sounds/fires...it's likely bad...if you pull one off and it DOES change (ie, stall/sputter/etc) it's good.

Thanks for the quick replies guys, much appreciated. I've tried to switch packs, still issue. There's new ones for 17 on rock auto all 4... I may order those and an o2 sensor but the flashing check engine light really scares me. Can I continue to drive with a misfire for a couple days till I can get it to a shop?

If it's continuously flashing I wouldn't, all that fuel is getting dumped into the converter and a new converter is a lot more expensive than a rental car for a couple days.

If you have an Advance Auto close by you can usually get close to RA prices by checking www.retailmenot.com for coupon codes and pick the items up in store.

Also I think you're looking at the wrong part, they don't have any ignition coils listed for a 4 pack at $17. Those are just the boots for the coils.
