What a difference... update on truck!

[Roadcuda]

the new mufflers make. i finally got around to installing the new mufflers I got last fall from Accurate Exhaust when they had their 25% off sale. Overall it wasn't too bad to do considering I was on my back the whole time. The biggest problem turned out to be the difference in muffler size. The body length of the ones' that were on the car were just 13" long and they used a 5" long extension pipe to make it fit. The new ones' I put in are has a body length of 20". To make it work I had to cut about 2 1/2" off the engine pipes! But it was all worth it 'cause the car sounds so much quieter, both at idle and when driving. I went out on the highway and at 65 mph I could actually hear myself think and hear the radio. And maybe it was my imagination but the car sure felt quicker under acceleration. Could having the right mufflers back on the car do that? On another subject. My '03 Ram is now showing an OBD code of PO137 Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2) This was found on OBD codes.com but I couldn't find anything specific to Dodge. Does anyone have a source for these codes?

Re: What a difference...

I had the same code last year on my Jeep. I found a wire bundle coming from the downstream o2 sensor had broken insulation on it which caused one of the wires to turn all green inside. I cut out a few inches of it to get to the good copper and spliced it along with some heat shrink and tape. Hopefully it will be that simple. Here is a guy with the same problem but a little worse that mine.

Re: What a difference...

Thanks Jim, I just bookmarked that page so I can find it quick. Now I know where to look first.

Re: What a difference...

The right mufflers do make a difference. Good to hear its pleasant to drive. As for the o2 it's usually the heating element that burns up with these new 4 wire sensors that I've delt with.

On another subject. My '30 Ram ?

so how in the hell did you get your hands on the 2030 prototype Steve? :acme:

glad you like your new mufflers

Re: What a difference...

I'm thinking of swapping mine out.I have straight throughs on at the moment,great for annoying the neighbours but tiring on long journeys.

I have Flowmaster Super 40's on mine. They're a bit loud, but still sounds pretty decent.

Once my carpet and headliner was installed things really quieted down.

rats, and I thought we had a Chrysler insider....

Can't figure this one out. I filled the tank today before I could look for the engine code problem. When I started the truck to leave I noticed that the engine light didn't stay on! :huh: When I got to work I checked and found that the code was still there. After I got home I disconnected the battery for half an hour or so. After reconnecting it and checking for codes, there were none! WTF, could the whole problem have just been with the fuel cap leaking? I know that can cause the engine light to come on. If that is it, why would it show that particular code! :crazy: :crazy: I'm just relieved that the problems seems to have gone away considering how close to Carlisle is since it's towing my bird down there.

Dad had a mid '90s Dode 1/2 V6 for a while. It would throw up a code, and the dealership finally tracked it down to the gas cap.

Hello Roadcuda,
I also have an 05 Ram 1500 with a 5.7 that intermittently throws the check engine light. Scanning comes up with P0137, bank 1 sensor 2. The code that comes up is left bank downstream O-2 sensor. I have wanted to change it but everytime I say lets do it, the light goes out. This has been going on now for over a year. It appears to come on only when the engine is a cold start. If I start it and go to the store or something, and continue to run small jaunts that never allow the exhaust to completly cool, the light will generally go out by the end of the day but only after a restart. I recently went from Maine to Rhode Island and back in two days. It never came on or off the whole trip. 700 plus miles (read:hi flow and warm exhaust temp) After a week of going to and from work for a week, back on it came on. As cj69RR said, I believe it is heating element related. But with warm exhaust, it is not needed. I hope this helps you feel that if this is your problem, It won't leave you stranded. But if you do get stranded, no one will say a word cause they will be starring at a cool Roadrunner on a trailer heading to Carlilsle! Just wanted you to know that others may be having a similar issue! Keep us updated on yor findings.

Thanks for that info. If it happens again I'll let you guys know.

see what you guys get fer buy'n those new fangly trucks.....

LOL! Fangly Truck? Describe that for a Back Woods Mainah! :toetap:

It won't leave you stranded. It reads the exhaust after the cat on that side to make sure the car is doing its job. Easy way to test the hearing element is to just turn the key to the run position, do not start it. First start of the day or after its cooled to where you can touch the exhaust. Put key to the run position and then feel if the o2 gets hot?

OK. If it gets hot does that mean that it's good? And thanks. I'll have to remember that if it happens again.

Oh Dave? That new newfangled truck is TEN YEARS OLD!!!!!!!!!!

 

[cj69RR]

A bad o2 will just give you a code and shitty has mileage because the computer won't adjust and go to a default mode and run real rich.

If it gets hot that just means the heating element is good. You will have to read the other wires to make sure it's actually reading the exhaust.
