you know, for quite a while now I've had a flat spot or two on WOT acceleration. Didn't matter too much on the starting speed, the acceleration just bogged down. It was baffling.
Of course I checked and rechecked for air leaks in the convoluted air tube, nothing showed up.
Yes, I changed the fuel filter, seemed like maybe an improvement, but nah just the good old placebo effect. (At least it didn't hurt anything)
Then by chance I looked at the area I'm pointing to in the photo. The factory bolt was missing! It must have worked itself loose over time.
Well a quick trip to the auto parts store and $1.35 later she was secured. Its a 6mm bolt with a 10mm head on it fyi. A black flange bolt would have been better, the plastic has an oversized screw hole, but for now the silver bolt with a washer works fine.
I looks like the motion of the engine block under torque creates an air leak here.
I immediately saw a difference, nice smooth acceleration. FYI, performance seemes to have even improved after a few drive cycles! Big smile driving around today.
Guess I'm all excited about such a super cheap fix with such huge impact, we don't get to see this too often.
Maybe someone else will run into this someday.
