So I'm here again with this socal 7th gen civic of mine.. Now after i work on my car about 2 weeks ago, i realized that the car was vibrating a little and after a day or so i got a check engine light, i scan the computer and the code was p1505 pcv valve air leakage, while the car idling i pinched the brake booster hose, pcv valve hose, purge valve hose that attach to the throttle body,no problem found, i unplugged the IACV and car make very little changes. I pinch the pcv valve hose and clamp the purge valve hose with a vice grip and unplugged the IACV Valve and the engine level dropped. I bled the cooling system for about half hour to get rid of trapped air with a spill free funnel and air was in the system but the rpm problem still there..the issue I'm having is that it would not come down as it should after the gas pedal is released and sometimes while idling it would rise for a few seconds and then fall.. Any suggestions would help please..i been on here so often about this car. Here is a video i made to demonstrate my issue.

Have you relearned the idle after all the work you've done? Last step in this DIY post.

yes, i did a relearn. Here is how i did the relearning process. I pulled the ecu main fuse, drove the car for awhile for the coolant to get hot, park and let it idle for 15 min without any load on the engine, i turn it off some times after the idling is done and go for a drive or i just turn it off and thats it. The book state that you should hold the throttle at 3000 rpm until the fans comes on twice then let it idle for 5 minutes,throttle fully closed and no load on the engine. But my question is, if you gonna hold the throttle at 3000 rpm, are you gonna hear when the fan comes on? I tried it twice and i couldn't hear it comes on. If you use a scan tool you can hear it because u can bed outside while doing it.

well, i did a relearn earlier this morning and the issue is stil there.. The rpm would start to go down and then stop for bout 10 seconds then drop to the idle range which is 800 RPM.thats not normal. I just drop it off at a shop to let the mechanic look at it. Why these Damn D-series gives so much trouble. I want to get me B or a k-series civic or acura. I heard about these trouble of these D-series.
i might get one of them older 98 civic.
