I could use a little help.
I have a 2k 5spd se with just under 30k miles.
Over the past month it has been developing a problem that is getting worse by the day.
Any time it goes from 2k + rpm to idle (like if I push the clutch in when approacing a light,) it drops well below the usual idle speed (to about 400.) This frequently results in a stall if I am not quick on the gas to tweak it back up.
I put a new air filter in thinking it might be short on breathe, but it didn't help.
I am having no other problems. Butt-dyno indicates no power loss.
The only mod I have is the otto fstb.

Any ideas?

 

Clean the throttle body ... Mine was doing the exact same thing ..

 

Thanks, I'll give it a try!
