Cylinder not firing?

Saturday evening i went out to my car which i hadn't run for like a day and a half, and started it up and the idle was very rough, up and down kind of idle, very inconsistent. When i accelerate it just progressively speeds up in a thumpy kind of sound, reminds me of a diesel or a big truck. Also have a great loss of power, so all around kinda sucks.

I'm thinking potentially a clogged injector as i don't believe they have ever been cleaned, or maybe one cylinder isn't getting spark, maybe a faulty spark plug wire or something of that sort.

I'll be checking for spark tomorrow after I'm finished school, but i'm just curious if you guys might have any other general suggestions as to where else i could look to solve this problem, or if any of you have had this problem.

Any input is greatly appreciated, thanks guys.

Distributor cap points or rotor? If your valve stems are shite, and the car sat for a couple days, the plug might be gummed up with crusty oil. Shouldn't take you too long to find the problem.
