How do you "stay" in PCM override?

I'm trying to set my min air idle and TPS. I can get into the overrides just fine and I can fully retract the ISC plunger, but it then says "while in PCM override xxx, check the engines rpms". If i try to go check the rpms, it goes back to normal, plunger out. How can I get it to stay in that override?

Also, could a slightly off TPS setting cause detonation?

Hope this helps

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

thanks for the replay, but i have the cadillac service manual. i've got all that same stuff. i can't find where it says how to "stick" an override, until you "unstick" it. This time, I"m trying to override and get the ISC plunger all the way in so I can set idle and TPS. I can perform the override, but i can't go back to check rpms or anything.

Sorry, didnt know you had it, the manual spells this out in detail in section 6E-C2-17. To override press warmer to increase and cooler to decrease. To override, it states on the picture I posted for you under KEY, Good Luck, Mike
