idling high 2k, 5sfe mt Options

[ILoveMySilly97]

The idle is fine all the time except when i drive it over 2k rpm. Then when i press clutch the rpm goes down to 2k and idles. The only way i can get it to normal again is to rev up to 2500rpm. Then it drops to 800. I'm thinking the diaphragm might be bad? This happens once in a while. One day it happens next day it'll be fine. A week later it does it again it sometimes a couple days later. Please don't say to clean tb.

another thing I've been thinking about this problem, because ive seen Dozens of posts here and other places of people with the same problem. Maybe it's just the accelerator cable itself has just gotten dry enough that it wont release fully on its own until you goose it a bit. because of the way it has to loop back around 270 degrees of a circle and it hangs up a bit.
also mine is not "mounted" in place like it ought to be, I had always thought the guy who put the last motor in just half-assed it, but part of it is just the way the cable runs like Eddy is saying. so maybe if we take the cable loose so that you can straighten it out and get some Teflon lube down it or something it might return back to idle on its own.
which is pretty much exactly what SAHEcelica was saying
