hey guys 88 SD eec question

Hi
Ijust purchased the 88 a couple of weeks ago, and as i mentioned in a prior thread I have a few dtc codes ( 21, 24, 81, 85, 41, 91.) I hooked up my snap on scanner and was only able to pull the codes without reading live parameters so my troubleshooting is starting to get a little anyoing especially since im not a ford mechanic, so the question i pose is there anyway of getting live parameters and how can i find out if the car is in closed or open loop?
thanks inadvance!!!
any info greatly appriciated!!

anyone?????
