Message	This issue is unrelated to the work I just did, as it was already happening before, but I'd hoped cleaning up all the connections on the plenum would fix it. Apparently not. So... a little hard to explain, but basically what I'm seeing is that my revs don't drop straight down to idle after I let off throttle. Instead, they will drop down to about 1.5-2k... sit there for a few seconds, and then slowly settle down to 900-1k RPMs. Almost like you'd expect it to behave it it was still being choked to warm up. But this occurs at normal running temp. Any ideas? Former Stage V addict... off the wagon.
