Let me preface this post, with the fact that question mark key on my key board is inop. Please keep this in mind, when all my questions are punctuated with a period.

I smoke tested my car, and found it had about 50 vacuum leaks. The 2 RH rear injectors were leaking, the intake elbow was leaking, and the throttle body, and IAC were leaking. I also got smoke out of the diaphragm, on the EGR valve.

I replaced or repaired everything that was leaking, and used AC Delco parts where I could, and re-smoked it. No more smoke from anywhere, except the EGR valve diaphragm. Exactly like the old one did.

Is this normal, or did I get another bad EGR valve. I asked around at work, and got about a 50/50 mix of normal/not normal.

When I looked at my fuel trims tonight, they were a little high, but not real high.

ST was around 125-127
LT was around 130-132
coasting, they both went to exactly 128

My idle was exactly 800 rpm, and the O2 sensors are working, and passed both tests using a Tech II scanner. The car still smells rich, and does have a miss at idle, but you can't hear, or feel it under load.

Hopefully Shoebox, or Injuneer can answer my EGR question, as it's driving me nuts not knowing.
