Hey Guys i need help.
I have a '98 Honda accord v6 with 81k miles on it.
When cold and started, the gears engages normally. But when heated up for just 3-5 minutes, the rev at idle state fluctuates between 1500 to 3500 rev/min.

Still under this condition the revers gear does not engage again. To get the revers gear, i have to switch off the engine and start again.

As soon as the rev begins to fluctuate, when I engage d4 or d3 the car jumps even when the brake is engaged and you can feel the impact as if you are engaging a manual transmission without the clutch.

The car literally drives itself with the leg out of the throttle.

When N or p the rev is between 1500 to 3500 rev/min. but when loaded it stabilizes at 1400 rev/ min


Any suggestion will be appreciated

Sounds to me like your IACV valve went bad. My wife's 99 V6 had the same issue around 90K miles. Pretty easy fix and IIRC wasn't too pricey, about $80-90 for the part.
