Major problems

[bigred90gt]

I checked the vacuum hose to the EGR valve and couldn't see anything wrong with it. I'll probably replace it anyways. Are the EGR valve and Idl air control solenoid expensive? I might just buy new ones this weekend. Lots more work at the restaurant. The SPOUT connector is plugged in. When I had it out to move the timing, the engine was idling fine. When I plugged it back in, that is when it started to stumble. This was today. I had planned to upgrade my MAF sensor to about a 76 mm anyways. If I am going to do this, should I just go ahead and get 24# injectors and a MAF calibrated accordingly? I don't plan on any power adders for a while. At least not until this car can be a strip only car. I figure I might as well replace the BP sensor while I'm at it. Can you get the SPOUT connector and BP sensor at an autoparts store or these dealer items?
PKRWUD, if the evap container is the canister jimberg speaks of, then, yes it is hooked up. The only problem I could see with the vacuum hose is that it was broken at one time, so there is a "splice" in it. The "spllice" is a piece of rubber tubing slightly larger that the vacuum hose approximately 3" long slipped over the ends of each half.
jimberg, What does it mean by canister circut failure? Can you replace the canister for this problem??? How important is this canister?
Once again, I can't thank you guys enough. I would be really broke if I had to take this to a shop. As I said earlier, I'll check the vacuum with the pump probably thursday and get back with y'all.
