How To Inspect Air Intake Hose?

[bicycleagent003]

Hi Mudders,

For starters, I apologize if this is a silly question. I'm STILL trying to fix this darn intermittent hesitation issue I've had for over a year.

How exactly should I be inspecting the air intake hose? I have taken it off and looked it over carefully, but I'm reexamining things again in an effort to figure this thing out. Do you hold it up to light, attach a vacuum to it somehow, try to blow air through it? I don't really want to try and flex it too much, but should I be doing that?

Thanks
Russell

Check for cracks.

Mine broke at the pleats when I tried to look at it. Easy peasy

Try spraying starter fluid around the intake tube (carefully) and if idle changes you've found a leak.

It gets dry and cracks at the "ribs" because that's where the tube is flexed most by the engine torquing, plus it gets hot.

In my experience I got a CEL saying the engine started running lean all of a sudden.

yeah, its cracks at the ribs and on the bottom part of the tube for the most part
