I ordered and put in GM p/n 1997227. which is listed for a deisel truck. made a plug adapter for it that would fit the male pins on the factory plug and then go on to the new sol. which also has 2 pins. I have also ordered an already made up adapter harness.this now gives me 14-15 lbs of boost now getting no K/R most times and maybe 1.2 deg some other times.as well as my question about the TPS on my prev post, I also wonder why I would get a different reading from the IAC sometimes.(always warmed up to 160 deg at idle). had it set to 20 with the TPS set to .44 with key on engine off, ran the car to work and came home, checked the numbers again when I got home and had IAC reading of 46. does this indicate that it needs cleaning and/or maybe a new one.
thanks for any advice

Sounds good, making progress... the IAC sounds like it is in the ballpark. In gear it tends to rise a little in park it is lower.. cleaning is a good idea if you haven't done it..
