Slight surge in idle

Slight surge in idle
Three days ago my idle grew a surge. It usually sits at 1000k, So now it is surging back and forth between 1k and 1800k roughly. It is only at idle and sorta comes and goes but it is constantly there.Generally I have been able to get surges out in the past by backing out some fuel at idle. I haven't played with the idle set screw because I broke the top off mine and need to swap it out, I did however back some fuel out with my PMC and that didn't seem to affect the idle the way I needed it to. I have quicky glanced to make sure my caps and hoses are all where they should be. So aside from an idle screw asdjustment what could be the culprit. Keep in mind that this started out of the blue, no work was done that could prompt something like this. I'm reading if anyone has any input.

Probably the TPS. Vac leaks are normally constant and don't surge. I had the same problem. Try to adjust it, but if not you can get one at the dealers for like $190.00. Good Luck.
