90 Accord - Replacing idle control valve

My idle is messed up and it is doing the bouncing idle thing. By this, I mean when it is idling, it will idle at 1000RPM then jump up to 1500RPM, down to 1000RPM's, up to 1500RPMs, etc. It is very, very annoying.

Well, I got the parts that I need off of eBay. Well, I have the idle control valve and the fast idle valve. If I am somewhat mechanically inclined, could I replace these parts by myself? I know new parts will be about $200 each and I don't want to pay a mechanic on top of that if I get the parts for $50 off eBay and I can replace them myself.

Thanks.

They are easy to replace, but you should use new O-rings and / or
gaskets. Do the fast idle valve first. The idle air control valve is
almost certainly not the problem. Vacuum leaks are a common cause of the
oscillating idle speed. See if you find cracked vacuum hoses and
connections etc.

 

Well, did that the last time that I had this problem about 9 months ago. Pretty much traced every vacuum line and the problem was still happening. Cleaned out the ICV and FIV and the problem went away. I am to the point of replacing them now.

Before replacing parts.... make sure that your idle speed isn't set too
high, and that you have plenty of coolant in the cooling system, there
should be a bleeder somewhere. If both of those are fine, then like the
other poster said, I would start with the fast idle valve.... though I'm
kinda cheap when it comes to that and I ignore what the service manual says
about not adjusting the valve and I try that first.

Also, the price from the dealer on the fast idle valve is only about $70....
and it's about $50 bucks at the online places.

Ok, I will look at prices from mechanics again. It needs to be fixed and it will cost me only $200 to get it done, why bother doing it myself because I will probably break something anyways.
