O.k. 93 accord and an h22 with a/t. I had this problem with my stock f22 and still have it: when I'm going uphill around 60-70 mph and let off the throttle and then push it down 1/4 way the rpms drop about 300, but if I let up a little bit (to about 1/8 throttle) the rpms go back up. So cruising say I'm at 3000, 1/4 throttle it goes down to 2700, let off the throttle a little bit to 1/8 throttle and the rpms go back up to 3000. WHAT GIVES!? fuel filter & o2 sensor have been changed. Problem #2. My trans only shifts at 6500 now when it was shifting at 7200 before... <_< thanks.
