for some reason the idle keeps fluctuating. but by much, maybe maybe 100 or 200 rpms. but i can feel it. would some injector cleaner help or something?

 

Doubtful, try looking for Vacuum leaks. Visually inspect your lines and splice connectors. I just found a 90 degree splice on mine only it was supposed to be a T and the other line broke off behind the T belt flange. Also check and repair oil leaks you shouldn't have any of those.

Bottom right corner of the hood has a vacuum system diagram to help you follow the system. Might be time to replace all of them anyway.

Also try replacing the Airfilter and cleaning the MAF sensor. You can buy a can of special MAF cleaner at the autostore. Don't touch it with anything just spray it.

If you suspect your injectors are clogged you should pull them and find the clogged injector. But I still doubt that's it.
