I have a 1989 Honda civic just had a rebuild what i thought was a blown head gasket turned out to be holes burned into 2 valves.since the rebuild it soots up the spark plugs bad it flashes codes 1 then 10 then 14.but before i spend a small fortune on all three could it only one of these causing the problem or could it something else

after removing it, you can clean it with an aerosol throttle cleaner followed by some spray lubricant. Its a possibility that it may do the job. after removing it, you can clean it with an aerosol throttle cleaner followed by some spray lubricant. Its a possibility that it may do the job.

I have a fast idle while cold and hot on mine and I'm getting a twenty short flash code on my 1991 honda civic hatchback. I believe it's the 1.5 engine but not sure. i replaced the AIC valve with a used one which may also been bad. i too cleaned both of them and it did not make a difference but I still wouldn't know if either one is bad so i'm not sure if cleaning it helps. i've seen videos on utube of cleaning them the same way mentioned with good results but that was on the 92-95 models. can you shed some light on the twenty short flashes and what could possibly be wrong with my car? i've checked and sprayed really well to see if there are any leaks, and when i disconect the the vacum to the AIC valve i can feel a vacum and when i open it up to air, it defenately increases the idle even more.
