hey everyone, been having an issue with my 07 accord, i have had this issue in the past but very randomly and once a blue moon. When i accelerate and i get to about 3k rpms it drops back to under 1k rpms and it will keep bouncing back and forth until i take my foot off the peddle, then it drops down to normal RPMS and i can continue but i can get past 3k rpms. i was explaining this to a friend and he thinks its the throttle positioning sensor. anyone have this issue before? what was the issue? need help asap as this is my only vehicle to get back and forth from school and work, thanks in advance.
