Problem shifting with rear Altus derailleur

Bike is a 2003 Gary Fisher Advance. I recently removed the front derailleur since the bike is used 100% on the street (I just leave it in the 48 tooth chain ring) and that derailleur was rubbing badly on that chain ring. In order to do, I of course had to remove the chain and as a result I decided to remove and clean the rear derailleur which was very 'gunked' up (it hadn't been cleaned since, well never).

Now with everything put back together, I am having some difficulty with the shifts. After using Sheldon's site, I have adjusted the high and low limits properly, but can't seem to make the index adjustments precise. Perhaps it goes beyond the adjustments? Here is the issue... when shifting from 2-3 on the rear cogs, nothing happens. When I shift from 3-4, it either shifts into 3rd or goes directly from 2-4. Everything other gear shifts perfectly fine. What do you think? I couldn't seem to find a decent answer to this specific issue by searching.

Thanks in advance.

I had an issue like this on my GT Timberline last year. I took it to the LBS, and they told me it was because of badly worn teeth on the cogs.

What happens when you shift 4-3 and 3-2?

Thanks for the replies. The downshifts so to speak (4-3, 3-2) are typically fine. Prior to removing the chain and rear derailleur this was never an issue, so I am thinking it is an adjustment or cable issue.

Clean and lube the cables.
Shifting to a higher gear entails loosening the cable. IF it's sticking in the housing, it won't retract promptly. You shift up another gear and then all of a sudden, the RDER springs all the way, when the cable breaks free.

Thanks Bill. I will give this a shot today and see if it makes a difference.
