94 astro rich smelling exhaust
Just purchased 94 astro that sat on the lot over a year. It was fine at test drive but began to run rough at idle by the the time I got off the highway, on the ride home (20 miles). Parked it in my driveway and it would not start. Changed plugs,caps rotor. Only started when I held pedal to the floor. Check engine light came on, code 32 and 23. Replaced EGR. Old one was clogged with carbon. Idles fine now but still have to apply pedal to start. Every once in a while it starts without pedal. Has Rich smelling (stinky) exhaust fumes. PCV rattles when shaken so I did not replace it, looks fairly new. I suspect water in fuel system. I am on 3rd tank of gas running to Empty each time and filling it up, adding gas treament. I can understand water causing starting problem but could water in the system cause rich mixture/stinky exhaust? Things are leaning toward the spider but I have to rule out any others first.
Any suggestions would help me sleep better. Thanks
