Default 06 1500 5.7 hemi Engine stalls, check engine light on

Help!
I just bought this 3 weeks ago. The day after driving it off the lot I noticed that the theromstat wasnt working and the check engine light came on. I took it back to the dealer and they fixed it.
The next night I noticed that none of the interior lights were working all of a sudden. They were working before I took it in. So, I went into the fuse box and noticed that the fuse for interior lights was pulled. Upon replacing it- the check engine light was back on! There were 2 other fuses missing, so I went ahead and replaced those too and miraculously, the check engine light went off. It has stayed off, however now the engine is stalling randomly while idling (stoplight, etc). Do you think it's all related? Anyone else have these issues?

It's very possible that the throttle body is clogged up with gunk, a common issue and very easy to clean. You can do a search in this section for a plethora of information about it.
But I'd make it the dealer's problem, sounds like the thing ain't been right since the day you drove it off the lot.

Also sounds like they "band aided" your original problem by pulling a fuse. Did they think you'd not notice your lights not working? I'd give 'em hell!!!

You are supposed to take the TB off and spray non-chlorinated cleaner on the BT plate and bore and clean it. You want to me careful not to get an in the electronics. The reason they say not to spray cleaner down the TB with it on the intake is because anything you spray off if it goes down in the intake and get digested by the truck. If you have ever seen a nasty TB you would certainly not want that gunk down in the engine.

I had the stalling while idling problem, and sometimes random 'chugging'. Try and oxygen sensor - but there are 4 on the Hemi. Pre/Post Cat on either the Left or Right side...so you probably need to connect it to the computer to figure out which one. I have replaced 2 already....Love my Hemi...

All has been ok since my last post. I put in premium gas and no more stalling, however today, my check engine light came back on. I have a call into the dealer, but I'll bet they will tell me to kick rocks. So....would a dirty TB cause the engine light to come on? grrrrr

Not usually, but prolly an EGR code, since they are about as gunked up as the TB. What's the code? Gotta pull the code to know for sure...

Man, that potentially could be a bad one. Hope you got some kinda warranty on the truck.

That would be a problem with your MDS system in the engine. That's the system that handles the transition from 8 to 4 cyl mode and back.

Possible causes can be insufficient oil pressure acting on the lifter locking pins, oil passages restricted in the engine, bad lifter or bad MDS solenoid.

Hopefully it's the solenoid...

P0420 Catalyst System Efficiency Below Threshold (Bank 1). It could be a bad cat, exhuast leak or a bad rear 02 sensor. How many miles are on your truck?

Lindengauthier,

The 5.7L engine is designed to use high quality unleaded gasoline having an octane range of 87-89. For optimum performance the use of 89 octane is recommended. The routine use of premium gasoline is not recommended. Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms try another brand of "regular" gasoline. Additional information can be found on page 282 of the owner's manual.

However, if you are having concerns, you may want to have it looked at by a Dodge dealer for a complete diagnosis. They will be able to confirm if a repair is necessary.

If you have any questions feel free to PM me.

So you would say to use octane 89? How much more is octane 89 anyway a couple cents?
