Misfiring Town and County 3.8L

[MASSMINI]

I have a '03 Town and Country 3.9 liter w/ 50K miles which just started misfiring. It runs rough, exhaust sputters and smells, and power is low. But it doesn't stall. Check engine light is on and I've read codes of P0300 (random misfires) and P1684 ("Driver 5 Line 4" - no idea what this means). My dealer read the same codes, had no idea about P1684, and wanted to start by replacing plugs and wires. I'm about to do that myself.

Has anyone had this symptom?

Replace the plugs and wires yourself, that should take care of your problem.

The p1684 I believe is related to the SKIM module for your skim key, possible an invalid or mismatch fault code

P1684 is a battery disconnected fault

seen a alot of the vans do this and there was a tsb that also required a reflash of the pcm and replacing wires and plugs for 04 that was a late 03 issue and thats covered under emissions warranty and so is misfire codes because the vehicles fails emissions testing at that point so do your plug and wire change and then let it misfire somemore

 

[MASSMINI]

Well I've changed the plugs and wires and they did not solve the misfiring problem. Still runs rough and smells funny.

philthy: Do you happen to know the TSB # that calls for PCM reflash?

There is no reflash for this model/year, Philthy thinks every TSB pertains to every vehicle. There is no TSB period

My next step is to swap out the EGR valve. Does this make sense? It appears to be on the back side of the throttle body just downstream from the butterfly valve. Is that correct?

Thanks in advance...

To me it makes no sense at all, first of all EGR would not effect a lack of power, it may cause rough idle or a slight hesitation. Why not have someone who knows what they are doing tell you what is wrong with the vehicle??

My first move was to take it to the Chrysler dealership - they could not tell what was wrong and proposed to start by swapping out the plugs and wires (for $426). Now that I've done that myself (for $80) I'll probably take it back to the shop. However, if I could find out what the next parts to be swapped were, and they happen to be easy, I'd do that myself also.

Well since you have a cyl misfire fault and you say the exhaust smells I would assume that it is getting fuel (rules out injector possibly) So I would think it would be a secondary ignition misfire? You paid the dealer money and they told you it was a misfire code did you happen to ask them what cylinder it was? The scan tool they use will determine what and how many cylinders are effected to help in diagnosing the problem. What are you gonna do when you throw everything at it and still don't fix it because its an internal engine problem such as a valve? Why not take it to a competent shop?

max you are wrong not all tsb applies to all vehicles nor do i think so boy oh boy u are starting to sound alot like stern

 

[philthy]

that sure wouldn't be u

You cannot reflash a PCM if there is no reflash available!!! When you connect to Tech tools and show all available updates...if there is no flash for it how can you flash it???? You keep telling people on here there is a TSB or a recall out on vehicles that aren't. The original poster is asking you for the TSB number and you still haven't answered him because there isn't one. Is this how you fix cars? shot gun repair?? Misinforming customers?? Take a deep breath the next time you post and read what you type.

no, i quit the dealer so i wouldn't misinform them or throw parts at it like you do.dealers don't pay techs to properly trouble shoot cars esp. dc techs just swap parts there is a tsb for a misfire and it was early04 and that van inquestion might or might not fall under that tsb give me your pass word to dealerconnect and i will find it for u since u can't seem to and u know as well as i do the most current flash will more than likely cover that misfire issue too since the pcm part numbers is the tech tool rule of thumb so it may not show that one tsb now dan you can oh i'm sorry your name is glenn but have become as arrogant as him that post has come and gone and so should you

the more arrogant a man becomes the less he can think

I understand why they let you go dirty.

just swap parts
there is a tsb for a misfire and it was early04 and that van inquestion might or might not fall under that tsb give me your pass word to dealerconnect and i will find it for u since u can't seem to and u know as well as i do the most current flash will more than

likely

You CANNOT relash a moduel if there is none.

You tell people on her all the time there is a TSB or recall when there isnt

philthy: Do you happen to know the TSB # that calls for PCM reflash? This poster is still waiting for an answer after you told him there is a reflash. well we are waiting for your reply??

cover that misfire issue too since the pcm part numbers is the tech tool rule of thumb so it may not show that one tsb now dan you can oh i'm sorry your name is glenn but have become as arrogant as him that post has come and gone and so should you

Do you want me to get you the post?

I dunno about anyone else, but I for one am waiting for you to put up, or shut up

let me refresh your memory though, in case you're forgotten

seen a alot of the vans do this and there was a tsb that also required a reflash of the pcm and replacing wires and plugs

if you know there's a TSB, then you should be able to find it, so please, back up your claims.

I don't know glenn, beyond here. I've had a few problems, and read others problems and he's always been clear, concise, and accurate in his help. For that I thank him. What little i've read of your stuff (this thread0 seems that you like to say stuff with no proof at all. All show and no go, lots of pep, lack of poke, all mouth and no trousers. call it what you will. thats the impression i'm gettng of you
