Hey after i drive my truck say 15 miles or so everynow ant then it will have a rotten egg smell. The CEl light is also coming on some.After you drive 15 miles or so when you pull up some where and put it in park it idles up and down and eventually levels out ..any ideas i need some help

Thats the smell of a bad catalytic convertor.

Would that cause a CEL light and the Hesitation and idling Problem i have ..Autozone cant read the code because it isnt a 96 or newer

Sounds like the cat is plugged up.

order up a new cat from jegs.com and take it to a place to have it welded in.

Yeah, your cat. converter is plugged. A clogged cat. converter can cause that kind of erratic idle, and that coupled with the sulphur smell is a classic sign of a plugged cat. converter.
