I repeated the KOER test to make sure. How about best 2 outta 3? I’ve run it maybe 10 times today, clearing the codes after each run. There have been several codes flashed. The last 2 times, engine warm, carefully executed, with the brake depression step included, was 632-632. No 536 this time. I guess the brake step is finicky.

 

Just to close this out. My problem was a faulty TPS. So, after 15 yrs the MAP and TPS went bad w/in 4 months of each other. When it rains it pours. Thx for the help folks; I'm sure I'll be back.
