I have 98 honda accord, engine light, rpm goes down

I am no Honda expert, but a similar problem happened to my ex sister in-laws Ford Taurus. The speed odometer would jump around and it had trouble shifting (automatic transmission). After driving it I changed out the speed odometer sensor on the transmission and it's been fine ever since. I changed out the sensor because if the cars computer cannot tell how fast the car is traveling then fail safes in place go into effect and the computer will do it's best to keep the cars rpm's down based on the speed indicator and not let it shift or shift properly either. If it's getting false speeds then it will shut down the motor when the speed gets to high and allow it to run as the speeds fall (jumping speed odometer needle). It effects the transmission shift points also. It will either shift erratically or not shift out of say 2nd gear, so that the cars engine can't get damaged based on what signal the speed sensor is sending the computer.

Maybe a fuse or relay.

That sounds like a possible vacumn leak

If the battery light is coming on,with the engine running,then have the alternator checked,it may not be charging.

for the door handle you have to remove the door panel disconnect the rods then you have a 10mm bolt one a side door handle.engine light is nor related to door handle it say one of the sensors is down you have to plug in and check it.speedometer it my be a fuse, my be the cable from gearbox or the instrument cluster itself

sounds like a possible bad ground wire, you will need to find out where these 3 items ground and see if they have a ground point in common.

replace temperature gauge and insprct/replace speedometer/rpm cable

The Speedometer head is faulty, replace speedometer head or whole gauge cluster.

I had the same problem on 1991 Honda Accord! It was the old AT fluid. I changed the fluid and all problems vanished! I had asked a Honda mechanic at first problem and he said make sure the AT fluid is good! Happy Honda Owner

Hi ....
On your HOnda accord V6.
The rpm is generated from the Distributor.
The more possible problem for erratic RPM is the cam sensor inside of the Distributor. But I guess you can't buy just the sensor.
And can afect the engine performance.

OK. I hope this information work for you.
I work on cars everyday. Thank you for use fixya.
