It's your "slow ideal valve" It's located on the intake manifold, near the driverside. There are 2 screws on top, remove the screws, Next get a flat head screw driver, now your gonna see a white plastic like saucer shape piece in there.. Now your going to turn the saucer shaped piece clock-wise and your screwing it back down, out the lid/cap back on, tighten the 2 lil screws, and start the car, the up nd low idle is gone..!!!!
I have a 90 honda accord ex, manual transmission with 160xxx miles.. when accelerating in any gears, it'll pause then accelerate.. doese it have something to do with the ignition systems or is my transmission no good? please help. thanks!

Recently bought a 1988 Accord. It revs high upon starting, and at lights stays at 900rpm. Told by dealer (over phone) it's probably the Idler Control Valve - $300!! Can I just take a chance and fix the plug over the idle speed adjustment for $0$? $300 is a lot of money to me!


Yep, you can do that. You can also use Seafoam (you can get it at parts stores) and clean the intake manifold out with that. The instructions are on the can, and it's super easy to do. Also, you can take off a vacuum line from the ICV, put a WD40 ... Honda Accord

Weird rev yes i swapped a h22a into my 95 honda accord. i got the swap from japan that came factory in the same accord, but when i got everything in and running i would give it just a little bit of gas (rev to 1000rpms) the car would rev up to 2500, then jump back down and just keep doing. but if i rev it passed 3000rpms it stops.

Gearbox Fault Hi There, The auto gearbox appears to slip in and out of engagement (revs suddenly raise whilst speed stays constant). It always drives and changes as it should from cold. When warm it starts to play up and is worst when above 2000 revs it feels as if it slips and revs rise accordingly. The next time its used it starts off ok again until up to temperature. Car is well looked after and has 60,000 miles on it. Gearbox oil is clean and does not smell burnt or appear to have any

When my taurus has sat overnight...or when it's cold. When I start it, it acts like it wants to die...then it revs up all of the sudden and seems fine. The gauge goes in between 0 and 1 for a few seconds than it revs up to 2 and slowly idles down to around one. I only have this problem when it's cold outside or if the car has sat overnight. What could be going on?
