Wow........ok...you obviously know more than I.....good luck again....




Pssst....Ghoste, you see what I mean now?

who cares what you know. I know what the problem is and honestly i dont need your input.

Bello, while Cooter may or not be on the right track with your problem different views and ideas never hurt. After all you came to the site and asked for help so if you don't agree, well gin and say thank you.

Far as your problem, I have not ran a repair shop for 10+ years now so I am way behind. But, from what I knew from yesterday tech I would agree with Cooter.

One thing I will warn you about is just reading the codes. Sometime codes for like a o2 sensor can be triggered by another problem. Had a lady come in come into my shop and wanted a O2 sensor installed, did not want a diagnostic ran. She knew it was the problem because Auto Zone pulled the O2 sensor code, and was not going to waste her money on a diagnostic!

Installed her O2 sensor, lite came on and I got bitched out?  Few days later she came back and apologized, had a diagnostic done at another shop. She has a vacuum at the intake that was triggering the O2 code.

With there being rattling in the cat's, good chances they are bad and hope it fixes your problem.

Cuda Ken I respect everyones input/opinion but what I don't respect is sarcasm and someone who acts like a know it all. I dont claim to know it all. im not that old and wise but I have diagnosed this problem for a few weeks now. Everything is pointing towards the cats. The car only stalls after warming up for about 5 mins. I did every possible test to rule everything else out. the only thing that I know for sure that are bad is the cats, the cat codes, the smell, the flashing engine light, the rattle, the sluggishness other codes etc. I wish it was something else, I do. but just to show that I am not a prick I will have another vacuum test done

Hey Cooter listen man. I apologize. Im just so frustrated with this issue. forgive me man and thanks for the input

Bello, that a stand up Mopar Person Style! 

Far as Cooter all wise being right?  I don't don't think so!  But he is right most of the time.

Again, good luck with your problem.

After Cooter pissed me off lol nah just joking I actually gave some thought to what both of you were saying and went out and tried to see if it was a vacuum leak. While the car was running I played around with the pcv valve and it duplicated the same symptoms........may be a bad pcv. i guess it may be a vacuum leak. i will check further tmw. I really appreciate u guys for not throwing the wolves at me

[cudaken]

Good Bello, now I wonder which cheesy faces Cooter will use?

Well today I checked for leaks and couldnt find any now its throwing P0300 random misfire smh

[maxwellwedge]

Hey - quit "Stalling" Cooter - We need answers!

Cooter dont like me lol

Hey Cuda Ken I think I may have found something. I had the engine running and it started to stall so i pulled the purge valve tube off and put it slightly back in. the stalling stopped. I restarted and it didnt cut off. Everything sounded better. I am going to let it sit for a couple hours and try again. Could this be the issue? If so tell Cooter Im ready to take my walk of shame

What are the specific code numbers. "Cat codes" means nothing. If its a 420 then its an efficiency code meaning the cats are cooked. However, before you go replacing them you need to fix the 300. If its missing, the cats are trying to burn that extra fuel and thats what cooked them. You also said the cats had broke up and come apart. How bad? make sure the muffler isnt full of cat material. But lets start with the bare basics and list all of the code numbers pulled from the pcm.

I was mistaken. the rattle i heard wasnt coming from the cats. i rechecked it. there is no cat code except the code reader i usded said catalyst but did not give a specific code. Here are the problems
code P0300 intermittently (if i clear it it doesnt come back unless the car gets to stumbling and stalling)
same with p1129 and 1128

the only codes that stay is P0031 P0037 P0051 P0057
I changed the o2 sensors but the codes remain

today I checked for vacuum leaks and found none then I played around with the purge valve tube right at the point of the car trying to stall and the idle became smooth. dont really know what to make of it or is that the problem

[c00nhunterjoe]

Those 4 codes are for each o2 sensor heater circuit. If they are not worki g it can throw the 1128 &1129 codes as a secondary fault. My money is on pcm or mouse chewed through the o2 harness but unlikely that it ate the 4 heater wires but not the rest. The 300 could be related due to the pcm not reading the upstream o2's properly

the thing is its a brand new pcm, the old one threw the same 02 codes. What do you think about what I said about the purge valve?

[c00nhunterjoe]

Youre missing thebpoint. Fix the hard faults. The o2 codes are the problem. If the pcm is good and thebo2's are good then you have a wiring problem.

I understand and thanks. I am going to take it to a good buddy of mine who owns a shop and let him take over and check for a wiring problem, vacuum leaks and fuel delivery. I'm not a mechanic and done all I know to do and its still stalling etc. Thank you so much for your help. I hope I can get this resolved but until then I'll drive my 3.5

And now you know why I say the things I do. You might get offended and frankly, I don't really care as the truth usually hurts, but you have to realize just how frustrating it really is to be fought at every turn when you don't understand, we were trying to help you.
I know what you were gonna say and do by the opening post. I do and deal with customers who think tge Internet is somehow gonna be replacement for experience....it is not. I'm about 80% sure I could fix your junk right here, but when you begin to think you have it all figured out....

The smart tech. Will tell you without a scanner looking at data, your pissing in the wind.

Cooter I have no argument. you were right. Thanks. Im not a mechanic but I was trying to find a solution since the dealer could not figure it out after paying hundreds of dollars. I tested the voltage on the o2 sensor heater circuit coming from the pcm and there is no voltage. seems like a wiring prob like Coonhunter said but what do I know?

These late model vehicles have so many different sensors and controllers that read the sensors it does get confusing. Its always good to see the scanner say MISFIRE on # 4 cylinder. At least you know to check that certain cylinder for a problem. It's not always that easy tho, an excessive lean or rich condition can cause an 02 sensor code. 02 sensors do go bad tho. I have learned that chrysler products do not work well with parts store parts. I have several jeep grand cherokees and usually go to the dealer if I need sensors for them. The 02 sensors can be bought from amazon or rock auto and they are an NTK brand which is who makes these sensors for chrysler. Good luck with fixing your charger and let us know what fixes it!!

thanks for the input. I disconnected one of the 02 sensors and checked the voltage on the pcm side and there was no voltage. Im not sure what that means or if I need a new engine harness or what. I tried to trace the connectors back to the pcm and it seems that there are no middle connections. it seems like the wires are going straight from the pcm to the 02. I may be wrong IDK at a lost

question:

Today I tested the asd in the fuse box (This is where the 02 code problem originated when I jumped the asd) . I removed the asd and tested where the asd plugs into (once with the key in the off position and once when key was removed from ignition) and it still had voltage (12v). Am I correct in saying that it should be off with no voltage when the key is in the off position or removed from ignition or am I wrong?

[Cooter]

ONE MORE TIME......SCANNER AND LOOK AT DATA.... somethings f'in with your fuel mixture causing the o2 sensors to go all the way to full lean or rich.
O2 codes don't mean o2 is bad ness. Without a scanner like the Snap On Modis, your screwed today.
