Hello guys, I have a problem with the idle on my Civic VTi 1999 sedan. The problem used to be RPM drop after revving, downto 200 and slow return to normal level. This was very frequent so I started to investigate this. Mechanics have cleaned the EACV two times but this didn't help, that's why I insisted on cleaning the throttle valve, and it was a big mess there. The RPM drop was fixed, but now I have a different problem - RPM jump After revving RPM goes down to normal level and jumps above for a while then slowly returns. I think this appeared after first cleaning the EACV. Any ideas?
