Intake smells strong of gas and is slightly wet inside.
I know fuel goes in there but listen.
I was cleaning my IAC yesterday, and saw my intake was slightly wet inside as well as dirty. I fid it weird that the intake would be wet in this manner.
Also what injectors do I need for a 2000 4.0. I have yet to get a straight answer. I heard that the dodge stratus 1998 injectors will work but I do not know the engine or numbers to look for. please help.
the iac was not to bad, but had lots of crap falling out of the hole.

The intake on a port fuel injected vehicle is supposed to be "dry" - fuel doesn't enter until the ends of the runners, near the head.
A fuel smell there isn't a big problem - unless it's strong (which means you probably have an injector not sealing.)
Fuel backflow through the intake may be caused by reversion - which shouldn't be happening through the intake. If it is, that could be a leaking intake valve. Have you lost power recently?
It would help to know more, but I need to chew on which questions to ask. But, I'd start with a compression test - just to make sure.

I do not have the oportunity to do a compresion test so that is out.

A dead hole is pretty obvious - a significant case of intake valve reversion is noticeable.

Reversion would cause pops through the intake... and rough running. It is possible. Check the airbox where the breather comes in. There is a little cloth piece that catches the oil. If your ccv system is stopped up and that cloth is missing you could be sucking oil in due to the location of the breather in the airbox.
If you're not losing power significantly and you don't detect any sort of "miss" (like having a dead hole in the engine,) then a compression test won't tell you anything new. Start with the fuel injection setup, then. (Intake valve reversion will kill base pressure in the cylinder, which knocks down compression and combustion pressure - both of which lose power. If the valve stays far enough off of the seat or is cracked/warped badly enough, you lose compression entirely and get a "dead hole," a miss, and a hefty power drop.)
