98 12 valve ehxaust smells like raw fuel
 
Ok so when i first start my trucj and engine is cold my exhaust smells like raw fuel.. almost enough to burn your eyes lol.. it very slightly smokes a greyish white color for about 5 mins.. is it my injectors leaking or jus because i have my pump tweaked?

It could be an injector dumping fuel into a cylinder. You would need to pull the injectors and see if one lost a tip or is wore out.

Did you ever figure out what caused this! ? Mines doing same thing and driving me nuts!

Get your injectors tested, to be fair though I have new 100hp injectors and exhaust doesn't feel great in your eyes at idle. I was airing up my tires with her idling the other day and had to take a break to wipe my eyes.
