I started to post a new topic concerning my 2012 2.4L stalling. But this post topic might fit my bill.It all began with the intake heater tee blowing apart and the engine over heating. Got codes P0304. After several weeks of replacing the lines, as I found new leaks, including the radiator hose filler neck, which had a crack in it and pulling the thermostat housing to reseal with new gaskets and formagasket, I got down to replacing several sensors as their codes would pop up. The camsensor on the back near the heat hose pipes that stick out from the thermo housing was toast....melted. Replaced and that code went away, then the crankshaft code started appearing, replaced that. (that one is a horror to do). Replaced the cam sensor on the front side near the fuel line, fuel rail connection when I got a P0000A Engine seemed to run better for a while, then started stalling again, not as bad. Tried cleaning all the connectors with electrical cleaner........that led to another nightmare I posted on electrical forum.........was thinking the cooling temp sensor needed replacing, but no codes.....I still get a stall or stumble (like theres water in the gas) when cranking up, it will just drop RPMS and returns to where it was. New plugs and coils by the way.........so I'm at a loss, until I read this post. Will check that and report back. By the way, the radiator filler neck I bought at Oreillys is made of some kind of thin plastic, similar to the original one and melted or should say, got hot enough that it started leaking and when I tighten the hose clamps it collapsed. Bought one on Amazon made of aluminum......no problems now. My opinion.....replace as you can all the connections made of plastic for the cooling system. IE: heater tees (hardware store brass plumbing tee with 2-3/4 and 1-1/2" barbs or Amazon has a complete setup of hoses w/tees made of brass)

1st problem solved. It was the battery. 2nd. problem, I didn't have one of the connectors to the pcm down tight like it should be. Engine fired right up. Now the major issue that got much of this started I'll post on engine forum.

Sorry, thought this site revealed the type engine. It's a 2.4 L VVT

Have had a ton of issues with my car. Cooling system, over heating, sensors going out. Took care of much of this and decided, whether correctly or not, to clean the connectors including the PCMs. Doing so I neglected to pay attention to the battery and it's low now undergoing trickle charging. In the mean time, I get a blinking red security light and no start condition. The music screen tells me to leave in "run" (push button start) and wait for the vin to be verified! Do I need to have the battery charged up before I do this? How long does it take the vin to be verified? Gotta take my wife to the doc in the am, this isn't turning out good.
