I've read the other posts here about 16v's with idle problems and bucking/surging. Unfortunately, I am now facing the same problem, although slightly different.
If I keep the rpm's under 3k, then the idle is fine, but once it goes over 3k, it will start surging and bucking. I've already checked the intake boots for cracks. I'll be cleaning all the contacts tonite and reading some more from my bentley.
If anyone has any ideas, or has seen a similar problem, I'ld love to hear about it!
Thanks,
Terrell

Sure sounds like its not getting enough fuel (fuel pump).

That or maybe a really clogged fuel filter? When I first bought my car, performance was down a little in high revs. I had a tuneup including replacement of the fuel filter. The car was WAY better when I got it back. I don't know how much the fuel filter had to do with it, but you might as well.

Not to rule it out, but just to clarify:
once the idle get over ~ 3k, it tends to stay idling too high, so it doesn't seem like it isn't getting enough fuel. If anything, it is getting too much fuel.
The problem is that the idle will stay at 2.5k for a while before it will 'kick down', or else it will race from 1k - 2.5k in rapid succession.

Hey Terrell,
If I remember correctly, you bought that '91 16V from me. The black one with the 17" Konig's?
Anyway...if that's my old car, it did this once before. I believe the problem was one of the AC lines pushing against an electrical connector by the fuel dist. I'd check it out... hopefully the car is treating you well. http://****************.com/smile/emthup.gif

Do this first and THEN if that's not it, you may be in the same boat I was in. NO rips, tears, or cracks but when I took the intake apart from airbox to TB and then re-assembled CAREFULLY, I think I fixed a SLIGHT sealing problem. she's purring now.
