Fuel Smell and RPM's

[98RED3.8]

About 15 minutes ago when I started my car, the RPM's were jumping between 500 RPM and 1500 RPM, running really rough, and noticed a strong fuel smell. I got out and went to check my exhaust, and it reeks of fuel. What is causing this? EGR maybe?

No Sea Foam. Just read in a some other posts that the coils, plugs, and wires may need to be replaced.

Got a better look at the smoke today and it is not blue tinted, its pure gasoline. White smoke and wont crank unless I press the accelerator to the floor. I am at a loss as to what's causing this.

is it PURE Thick white smoke and NOT normal exhaust smoke from cold weather? That would indicate a big problem.
yea, I'd do a compression check

Re: Fuel Smell and RPM's

It is a mix of the two. Its not a complete white-out behind the car, but it is definitely gas fumes coming from the pipes.

Re: Fuel Smell and RPM's

Just tried running Slick50 Injector Cleaner. Let the car sit running for about 45 minutes after I added the stuff and no change. Still pouring white smoke out the exhaust, RPM's fluctuatuing, and when I shut the car off, I noticed a hissing sound coming from the driver side valve cover area and some smoke from the same area.

Re: Fuel Smell and RPM's

Im assuming it's probably a bad thing that my oil smells like gas?

Re: Fuel Smell and RPM's

So I took the car in to have a diagnostic run on it. I pulled into the chevy dealership service area and when I got out there was gas pouring out of my exhaust pipes! They hooked the computer up and got the code for my rear o2 sensor and that was it. They tried to tell me that I need a new head gasket because they couldn't figure out what was causing the misfires and the gas in the oil. I asked to see the diagnostic report and they refused to show it to me. I left and took the car back home. I'm hoping that it just needs a full tunes up and maybe some new injectors. I'm assuming that once I get this figured out, I will probably have to replace the exhaust as well, due to all of the gas in it. Any help or ideas as to what is wrong with my car would be greatly appreciated.
