high idle after spark plug/cable/distributor cap change

hey there

I have a 1998 V6 4x4 dakota. It has 88k miles. I just changed out my distributor cap, rotor, spark plugs and cables. good thing because one of the distributor cap connectors and cables was corroded.

Now my idle is at 1000rpm instead of the stock 750-800 rpm it was before! I can't find any vacuum leaks or anything else I might have caused while doing these things. any ideas??

thanks
