I have a 93 toyota corolla. I recently started getting a rough idle when i am at a stop light. After accelerating, no more problems exist. If i get down to a slower speed, then it will start to act up again, if it comes out of it, i get a surge of speed. I changed the spark plugs but the problem still exists. What else should be checked? Will it be expensive? Is it a basic diy?

I would check for a vacuum leak, you could be sucking air from some where. You might also want to check the air filter, you would be surprised at how much better the vehicle runs with a new air filter. I don't think it is something difficult, but migh be difficult to find, especially if it is a small vacuum leak. Also check the fuel filter. Good luck.

You have a major vacuum leak, Check all the vacuum lines attached to your air filter tank ,check the carburator vacuum line hook ups,and check the other lines,but it sounds like the line on your pcv valve is broken or maybe the pcv valve is stuck open.Hope this helps you.Good luck.

it could be a bad plug wire or a gas filter.
