Revving Up When Warmed Up-lifting Pedal Helps??

I Have A 91 DX 1.5 Sedan And Have Had some issue's with the idle .so i removed the iacv cleaned it out,reset the ECU and it still revs up when fully warm out or after 15-20 min of driving.now it has only surged 3 or 4 times meaning UP & DOWN . it more revs automatically and the only way to bring it down is to put my foot under ACCEL & LIFT the PEDAL UP.
I also have no CEL on dah but on ECU I get A 3,7,14,15
I have also pulled the iacv and it brung the idle down,THREW A CEL.but one time it didnt do anyhing.
also i have checked for vac.leaks and nothing so far.
any suggestions on what i could of forgot
oh yeah tps unplugged made no changes
thanks

If pulling the pedal helps, double check or idle screw and the throttle cable - the throttle cable maybe too tight and not letting it go back to idle.

thanks for the help, I was thinking the same thing but doubted myself.looks like all the vaacum hose's have been changed not that long ago.so i am assuming last summer the previous owner had similar problems.

i agree with 4g4d, sounds like the throttle cable is too tight, or its binding. look to see if theres a kink in the cable anywhere

oh yeah guys
when i cleaned the iacv there was no screen on either round holes ?does this matter

no it doesnt

I had the same problem with my CRX dx, so I prayed the throttle cable at the trottle body and it went away, I wasn't getting any codes though, it was only the throttle cable

thanks guys im still checking and will check
the throttle cable again.hope thats it
worst case I can pull the iacv off my hatch but then my girl is gonna have to deal with it :)

WAIT! mine started doing it again, not as bad though. I shouldn't have said anything. I guess I am going to have to actually do something with it too.

I had a similar prob with my stock motor where the throttle pedal wouldnt go all the way up. I ended up figuring out that the spring on the throttle body got weak, I just removed it and trimmed about 1/2" or so off it, bent the end so it would hook to the body and it worked. It made the pedal come all the way up so I didn't have to pull it up with my foot. I hope that makes some sense

somewhat
im starting to think my iacv might not be screwed up and maybe the throttle cable or spring.I Know im gonna jinx it now but so far so good.
thanks for any input guys

well its back
and Im convinced its the Iacv now since when I unplug it drops rpm.so time for a new one or ebay one.sucks hope its doesnt start acting up when im doing my inspection tommorow
thanks guys for all the help
