New Injectors, now idle problem

I have a 1991 T/A, WS6, TPI 305. I was having trouble and took it to my local dealership. It turns out I had two bad injectors. I repalced these injectors myself tonight. The first time I started it up, the idle was at about 1500 rpm's. It wont come down for anything, I drove it around, but it still idles extremely high. I am clueless. HELP

It could easily be a Vacuum leak. Try a Vacuum gage/listen for the whistle!!
If after you are SURE there are no vacuum leaks, then do the IAC/TPS adjustments.
