Oh....here are a few more things you can "visually" check.
1) Check the vacuum lines are hooked up to the UIM as described above.
2) Check the little green vacuum line that is hooked up to the EGR Valve.
3) Check to see if the Fuel Pressure Regulator vacuum hose is hooked up - You might have to remove the throttle body to check it (I can see my FPR but not the actual line hooked up to it in my car w/ everything connected).
4) Be sure the two hoses that are connected to the DPFE sensor. That's located right under the EGR valve attached the actual block - in your case, its most likely an aluminum box that almost looks like an oversized cable splitter. An electrical connector and two hoses connect to it...(I doubt they're off cause I'm pretty sure they would case a CEL to come on while driving)
The next time the car stalls, be sure to check to see if the fuel pump is primeing it correctly. On my car, it was working ok when the car was running fine. But when the car stalled, the pump acted up BIG TIME (by hearing the noises!!)
Man...just drive down here to Woonsocket and I'll see if I can find something wrong. lol.
