Go to this Website, check to see if your cam gear timing marks are lined up, you can remove the top inspection cover and have someone keep lightly bumping the starter until the marks are straight across from each other, it's very hard to see them, if they are not aligned this can cause a rough idle and even cause the check engine light to come on, if more than one tooth off.

I forot to mention that the valve cover gasket can Not cause a rough idle, it will only leak oil, there are four rubber seals that go around the spark plugs that also should be replaced along with the valve cover gasket, they sometimes come with the new gasket.

i changed the valve cover gasket and the mechanic that did this couldnt tell me what was wrong with my car. it still idles really bad and told me that i should get a scanner to get it checked..
the car runs pretty fine otherwise and wanted to get the timing checked as well. i will try all my possibilities...... thanks......

Did you have the timing belt changed before the rough Idle? if so was the Idle okay before that? Does it sound like a car with a racing cam at an Idle? if all these answers are yes, then Most likely the person that changed the timing belt has one or both of the cam gears a tooth or two off.this will require the same procedure and time as if your replacing the timing belt all over again, the trick to the 2g non turbo engine is to align the all of the timing marks to TDC then make sure that the TDC mark on the Crankshaft is 1/2 tooth to the right of the mark on the block before routing the belt around counterclockwise, once the belt is on then all 3 timing marks must line up when number 1 piston is at TDC, rotate the engine at least twice to make sure they stay aligned, you can even start the engine with the cover off and just make sure nothing gets caught up in the timing belt, let it run a few minutes, shut if off and recheck the timing marks again before reassembling everything.If they are not aligned you have to remove the timing belt tensioner again and align the marks again, sometimes it takes several tries before you get it right.
