I have a problem with my trep =(... I have looked & browsed for this rough idle & plug search.. changed plugs yesterday.. one plug was full of oil, as well as the end of the tube/coil end.. Ck engine light is still on & yest. morning before changing plugs.. light was blinking! Per the manual.. this states severe cat. converter & power loss will soon occur.. restarted engine.. & then light was steady again.. Codes are 13, & 43.. Rpm's @ idle go up & down slightly & car shakes pretty bad in idle.. Mopar wires are on there, should those be replaced, I know it's a pain.. would rather not do it. Anything else I should do before I bring it into shop this coming week?!
Well, the code 13 refers to the MAP sensor vacuum system. This sensor determines the changes in engine loading and the PCM uses this to determine fuel delivery and ignition timing. Did you check to see if all the vacuum hoses for the MAP sensor are connected and OK?
The code 43 refers to the "Peak primary circuit current not achieved with the maximum dwell time." I think this has to do with the ignition or fuel.
My suggestion would be to make sure all the vacuum hoses are hooked up before I spend money on a new MAP sensor (~$100). Maybe this is one of those "take it to a garage" type of problems.
My 97 trep 3.5 has code 43 but i brought it to a friend who owns a shop and he hooked up his cpu to it and said its probably my intake gasket which is making it run lean i guess also both motor mounts are shot in mine which is giving it an annoying shake at idle
It sounds like you are having the same problems as I am. Look through this thread to see if any of this info will help you out. More than likely you have a leaking intake manifold gasket. As for your spark plug tube that has oil in it, I don't think that is a major problem. It just means that you have leaky O-ring gasket(s). This would not cause your plug to not fire.
Btw Paul, I concur with joss. My #4 sparkplug has been half-immersed in oil (and a little for the #1 plug) for about 6 months or so (I’m ashamed). I haven’t had any idle problems during this time period though, nor any codes.
Having said that, I suppose these plug boots can only be immersed in oil for a limited amount of time before some oil makes its way into the dielectric material of the boot and causes misfire problems. I would go with what joss said first though—check for an intake leak, which can apparently cause a lean condition creating misfire and multiple code 43’s.
If the intake leak is ruled out, then change your sparkplug tube o-rings (and maybe tubes themselves too) and your sparkplug wires. We’re both going to have to do that eventually anyway.
The infamous code 43 surfaces once again! My code 43 was caused by a leaking intake gasket... changed everything: plugs, wires, ignition coil... had engine timing reset- nothing helped. Hope it's less painful for you than it was for me bro.....
Thanks guys for the replies.. Much appreciated.. gonna bring it in this week to my mech. to look @.. How much would a new gasket run me just say... & BTW.. any more things possibly to ck out let me know =)
Had trouble starting it this AM.. had to give 1/4 of gas while cranking... uggh.. on way to work.. Ck Engine light was blinking again.. then went back to steady.. gotta get this thing cked out!
The actual gasket is only a few bucks I think. The labor is what kills you- I think the job cost me close to $200... The Dodge dealer waives the $70 diagnostic charge if you let them do the work. It was like night and day when they changed it... the check engine light never came back and the engine runs just as smooth as can be at 114,000 miles All cylinders are firing and power has returned. Gave me a pretty big scare because the first mechanic I took it to said that I needed the engine rebuilt for $3500- low compression was causing the #1 and #6 cylinders to misfire. Dodge did a compression test and it was on point
Well.. Mechanic just called & he said he changed the wires.. it runs a lil better.. but still very rough.. he said Injector # 5 is going.. he said total with out tax will be $370.00 :mg: so.. there goes more $$$ I don't have... :crazy:
Anyone think that is kinda high?! or normal? Napa shows injector for $59.00 approx.. wish I could do it myself.. but guess it's kinda late for that now..
Well.. after $425 picked the car up tonight.. but it's still not fixed.. on report.. it said car must be driven to be given time to burn of residue of non working cylinder all that time.. came home.. disconnected battery.. retrained tranny.. & ck engine light was off.. Went an hour away to Hartford CT. tonight, made it there.. seemed ok.. still was a lil rough.. but better.. seemed to have more power too.. now.. when I started car to come back home.. ck engine light was BACK ON & idle was a lil worse.. but still not as bad.. mechanic replaced wires & #5 fuel injector on cyl. 5.. WHAT IS WRONG.. PLS HELP!!
Did your mechanic ever pull the codes using a scan tool? These are supposed to give a much more detailed analysis of what is wrong with your car. I think he might just be taking stabs at what could be wrong as opposed to what is wrong.
Ya, I'm not sure I buy off on the bad fuel injector theory. When I had my recall work done, one of the mechanics dropped an injector and decided to reinstall it and hope for the best. I drove the car and it ran absolutely horrible. I could barely get it turned around and back into the shop. IOW, you'll likely know it when you truly have a bad injector.
This is beginning to sound too much like my experience... change that lower intake gasket!
Now, my experience with the scan tool: the scan tool gave a readout that said "random multiple cylinder misfire" and that's about it. The dealer had some other computers also. One computer showed each cylinder and the variance on the 2 cylinders that were misfiring. Even with all that, the technicians were still somewhat unsure of what was causing it. They changed the plugs, wires, coil pack... still didn't help. Then they said the engine timing needed to be reset... that cleared up the misfire (not the crappy idle) for about 24 hrs and the next more code 43 came back to see me again... blinking check engine light and all. I took it back again and they changed the lower intake gasket. That cleared up the idle, the code 43, and the misfire. Please change or at least have someone check that gasket! Hope everything works out bro.....
Yea I hope so too.. I talked to mechanic 2 days ago.. when I first brought it in.. I told him about cking the gasket.. supposedly he put it on the scanner.. he said he found cyl. # 5... misfiring... he said it's probably not that bad.. he had the car for 2 days.. & when I went to pick up the car last night.. it was idling rough & he didn't clear the code(s) off to get the ck engine light off.. so.. like I said.. seemed like it had alot more power.. I reset ck engine light by disconnecting battery.. & it was off the whole hour drive.. on way home a few hours later.. car was almost like it was b4.. with that ****ing light on again.. I'm pissed.. I am not paying this idiot any more $.. I got news for him.. I TOLD him to ck the gasket....
Isn't the #5 cylinder code the magic code that leads you to the lower intake manifold gasket? I heard others had said that the #5 misfire was the result of the bad gasket.
So how should I go about telling this guy I am not paying anymore for repairs.. since in beginning I told him to ck Intake gasket.. from what I found online @ work today.. too.. one person said in a site.. This is where the vacuum leak normally is in the intake manifold port for CYL #5.. which is the cylinder that was misfiring on my car... :mg:
Hmmmm. 2 different cylinders were misfiring in my case... I don't think that any tool is going to display "leaking intake gasket"... I can only speak from my past experience- I'm nowhere near a mechanic... The misfiring in my case was a direct result of the leaking intake gasket- I'm sure the Dodge service department has the most sophisticated equipment available to troubleshoot their own damn cars and nothing ever told them exactly what it was... I feel your pain man- hope you get it taken care of soon bro.
I have also had the code 43. One time it was the intake gasket and the other time it was low compression on the drivers side. This resulted from a broken camshaft bolt.
Well.. car is going back in shop tommorow.. talked to mechanic.. & after I did some research.. it's pointing directly to the intake gasket.. so.. I TOLD him to ck it BEFORE doing anything else.. he said "he'll take care of me" HE BETTER!
Well... according to mechanic.. I just called him & he said the misfire came back because there was residue/garbage as he said it around the cylindar that wasn't firing all that time.. so he's cleaning it up & it should be ready to tonight.. Hopefully it's fixed this time.. why he didn't do this before i picked up car is beyond me.. especially for $425.00.. but hopefully this time it'll be fixed.. We'll find out tonight
