Check your air tube from air mass meter to throttle body. Remove from car so you can see it all. If any cracks or holes, replace it.
From what I've been reading here it sounds like your problem may be the air mass meter (MAF), which you cleaned. Cleaning doesn't always do the trick. In fact most cleaners would probably damage an AMM, and are labeled "Do not use on air mass meters". I've only seen one cleaner made for amm's, made by CRC - the makers of electrical contact cleaners.
Test amm by disconnecting.
Be sure ignition is OFF before disconnecting.
Then start it and see if it's better that way.
If better, problem is the amm.
And be sure ignition is OFF before reconnecting!
Best replacement (dollars for value) is usually a known working used one.
For which years and types are a match, see AMMs listed at fcpgroton.com
The last 3 #'s on the amm are the identifying number. Typical are 001, 007 (?), 016.
If you have a friend with matching AMM borrow it long enough to try it. Better than spending the money on a replacement, just to try it. Self-service junkyards (you pull the part) are probably the least expensive source for a keeper; I paid $50 at such a yard.
