recently my 06 1500 quad started spitting and hesitating, then the check engine light came on. I ended up taking it to dodge to see what was going on. they said i needed to do plugs and a computer update (has 65000 kms). so i did that. It was fine for about 3 days then the check engine light came on again. This time with no driving problems at all. I took it back in and they said the code was telling them it was the cataylic converter, but they were hoping that it was just a computer glich, and turned it off and sent me on my way. 2 days later the light was on. Again they said it was the converter and it needed to be replaced. Now i have taken it for an E-test and it passed with flying colours, and i have no symptoms of a faulty converter, but the light is still on.
Anyone with any ideas before i have to shell out 1700 bucks for a new converter!!!??

 

can you give us the code? that the engine light produced? any engine mods?

 

Faulty O2 sensor or wire, more than likely the rear O2's if its saying your Cats bad.

 

Also $1700 for a new Cat is WAY to high, you can get NEW high flow magnaflows for $60-$80 a peice.

 

I'm thinking bad rear O2 sensor as well.

 

Cycle the key and find out which code it is. That will help to figure out what it is. Does sound like a bad rear 02 sensor.

 

should be under warranty. emissions warranty is alot longer than regular warrenty....actually i think its close to double

 

i dont know what the code is, how does the key cycle work, 3 times on and off ? I was thinking that it might be a sensor as well. An emissions test would still come out ok with a bad sensor would it not. and it would with a faulty converter.

 

If the rear sensor was bad it would still pass a sniffer test cause the cat would still be doing its job. If the cat was bad it wouldn't pass.

 

Well I think i am going to try replacing the rear sensor and see what happens. Thanks for all the help.
