When I start my car initially, it starts up fine, but after 5-10 seconds the rpms start dropping really low and sputters, then dies. If I flash the gas quickly it is just fine.

WTF?

lol.. It just started doing that, so any ideas of what to look into? Also the other night, it started loading up, felt like it went incredibly rich at low cruising. I was doing 20mph and started shaking and wanting to die til I got on it harder. Its done that to me 3 times now.

It's completely stock other then Ebay clutch, downpipe, intake, and FCD.

 

Probably a big vacuum leak.

 

And check the TPS adjustment, as well as the function of the BAC.

 

check all hoses for the basics. then move to bigger/other parts from there. Troubleshooting can and will be a pain. get the haynes manual.

 

Yeah, sounds like a vacuum leak to me. Good luck

 

any progress?

 

Oh, another suggestion is to temporarily remove the FCD. I've seen a few melt/fail and cause the engine to run crazy rich.

 

check the iac valve
