That actually doesn't solve the problem. I did that, and it proved to be only a very very very partial job. There are several little "chambers" inside the IACV that require direct spraying and rubbing w/ Q-Tip or cloth. To be safe, I decided to just go ahead and do the full job. Once I opened it up, I noticed that there are other chambers that the spray-in-the-hole-method CAN'T reach.
The problem will come back for you, as it will for everybody else. But in your case, it'll be a lot sooner.
The thing I found that had the biggest impact on the slow/rough idle problem was the small wave/spring washer in the electric motor of the Idle Air control Valve (IACV).
I had tried all of the cleaning and maintenance actions detailed above and found that it made some improvement but did not fully correct the problem. Then I remembered reading something in an earlier forum stating the engine would not idle at all and stall because the wave/spring washer was left out when the valve was reassembled. So I removed the solenoid/DC Motor component of the IACV and took out the wave washer and slightly increased the amount of bend on the washer (don't overdo it) and therefore putting more tension on the mechanical gate of the valve, therefore providing a dampening effect. I placed the washer back in the housing and re-installed the solenoid assembly and found that it was a little spring loaded when I tensioned the 2 securing screws. The engine now idles correctly and the slow/rough idle problem has been remedied, for now anyway. I will continue to monitor it and post it if the problem returns. All the info I have been able to use from this forum was excellent and I am very thankfull to everyone that has contributed and I hope this little note will also help someone out else out there. Cheers
