Ok so, I had the same crappy idle with my 95 that everyone seems to be having. I did a full tune up, that helped some. Cleaned the IACV, didn't help. Checked my TPS, it was fine, MAF ground was within spec, but I regrounded it anyway, and that helped a good bit. It quit jumping around but I still had a slight miss at idle. I had an EGR code tripping the MIL, so I finally broke down today and tore it all apart, cleaned it, and replaced all the vacuum lines I could get to. Reset the ECU, and now it idles rock solid and smooth My EGR tube going into the headers leaks a tiny tiny bit :angry: , but I'll have that straightened out by the end of the week. I've noticed tiny (barely noticeable) fluctuations in the idle, and my best guess is injector O-rings, but I'm going to stick the car on the smoke machine at school this week to make sure there aren't any more leaks. Oh, yeah and the tube going from the EGR passage into the bottom of the BPT valve looked like it had exploded, so there was no way it was working at all. My old sentra did the same thing, I'm guessing it just overheated.
