Gents,
I'm in a pickle. Like so many other ppl my Accord isn't idling correctly. I'd like the opinion of those who have solved this problem before. And yes I have searched, I'm hoping for some insight/opinions. Here goes:
The A20 idles between 1200 and 1500 rpm when it's nice and hot.
The Fast Idle Air Valve has been replaced (5yrs ago??) the internals are bright and clean and the threaded in disc is bottomed out over the plunger. I took off the cover of the FIAV and watched/felt for any movement of the plunger while the engine was idling funny. There was no movement at all.
The Idle Air Control Valve has been replaced [(5yrs???) the inspection stamp on the unit indicates a production date of 2005]
A test of the IACV was performed IAW this procedure: http://www.ehow.com/how_5560848_chec...rol-valve.html
The test produced an ohm reading of zero and the unit was cleaned with electrical parts cleaner.
After driving to heat the engine up again, the problem persisted. When I switch on the A/C the idle problem goes away. The IACV opens up the allow the engine to compensate for the increased load, which tells me that is does function in some capacity. (?)
When I unplug the IACV the erratic idle continues for a bit then calms down to a normal, if not a bit low, idle.
No codes or SES lights through out this process.
So, what do ya'll think:
Should I plunk down the $187 for a new IACV?
Take the car to a dealer and pay out the nose and let them figure it out?
Drive it anyway, turn up the radio and forget about it?
