confused Stumble on acceleration

My '93 Taurus (160K miles) ran great until it ate the distributor drive gear. I replaced the distributor and attached module, and set the timing to factory specs with the spark sensor unplugged. The car now starts easily, idles smoothly, and cruises great but has a massive bog off idle. The colder the engine, the worse the stumble. I have checked for vacuum leaks and found none. What would be the next likely problem?? Thanks

Unplug the MAF and see if it runs better.

I unplugged the MAF with little change. I then removed it and cleaned it with MAF cleaner. It still stumbles when cold but runs better than it used to warmed up. Should I replace the MAF or keep looking??

Re: Stumble on acceleration

I'll second the IAC change. I know if it's not too carboned up you can clean it with carbon cleaner. But, be careful, if you move the plunger more than 1/4" or so, you'll need a new one. If you can clean it, you'll save yourself some bucks. Cheers.
