Add me to the list, I think.

I haven't experienced what I would call low-end power loss, but I've noticed a "bump" around 3,000 RPM, where things would get suddenly stronger, so I suspected something was going wrong on the low end, just not bad enough to notice, without the abrupt feeling transition.

I snugged up the connectors on the intake side (couldn't immediately spot the exhaust connector, so I thought I'd try the intake connector and see if it made any difference), and things feel much smoother as the engine revs from low RPM to high. No more "bump." I'll drive it a bit more to confirm, but it was easily repeatable before tonight, and now it is not.

Because... Grocery Getter.
