View Full Version : Idle control solenoid A20A4

So my '89 Accord EX has decided to stop idling recently, and I've troubleshooted it down to a solenoid which can't decide whether it's open or closed (linking inlet to throttle body).

Unfortunately because in NZ where I live, nobody seems to have these old Accords -- finding OEM parts is incredibly difficult. I've bypassed this solenoid and the engine is running fine (albeit idling at 1100rpm warm), however I know that this isn't the best sort of fix.

Is it worth even bothering to fix this issue? I'm considering getting a B20 or maybe even H22 swap at some point in the future, and since the engine at least actually runs I guess I'm fine until other issues arrise.

I've looked on ebay but I don't seem to be using the right terminology to find this part.. I'm happy to upload an image of the part in question.

Thanks in advance

try to take if off and clean it with brake clean. Mine had build up inside and once I cleaned and flushed the cooling system it did not have the same idle problem.
