Truck smells like vinegar
 

Truck exhaust smells like vinegar or rotten eggs or something. Definitely doesn't smell like diesel exhaust. Any ideas?

do u still have the stock exhaust on it? ive heard of gassers smellin like rotten eggs when the cat is clogged, but idk bout diesels if they do. good luck figuring it out :U:

Run er hard down the highway on stock or level one on the Bullydog. It'll help clean the cat out.

if its not the cat check your batteries! on are tow truck which is a 04 Dmax i had that awful smell and i check the batteries and one was boiling over with acid!?? im not sure what causes that but if it is that just change BOTH batteries.

Hey, thanks for responding...I was beginning to think everyone thought I was crazy.

Checked the batteries...nothing.

Was thinking about the cat, too. I've run it pretty hard down the road, and still has the stench:humm:. Smelled my oil and my oil smells like it a little too. Gonna change it and use Delo instead of that Rotella garbage. Heard that contributes to the funk, too.

Taking off the damn cat today...I'll see what happens and fill you in. Thanks!

good luck, and remember to let us know if the cat fallin off today

I know it's been awhile, but I finally got the cat off and stock muffler. Added a Donaldson muffler. Definitely was the cat backin up that made it stink. Truck sounds sweeeeeeeeeeeeeeet now. Now, have to make my intake and the world will be right....

Ya mine was the same, smelt real bad, took the cat off and now it smells like a real diesel should..

Someone planning to make pickles forgot to tighten the jar after playing with the cucumbers? :ouch:

I have no idea but you never know.
