hey guys i have a 89 honda accord lx carb and when its cold it revs up to 2500 rpms or up to 4000 doesnt want to come down. what should i do???????

 

On top of the intake there should be an adjustment screw, adjust counter clockwise

 

Ps. I have trouble finding the fuel pump relay, Ive looked in the computer it say its under the driver side dash. I looked really hard and cannot find it, if any one can send a detailed location, possibly a pic , it would be much appriciated. Ps. Its an 87 honda accord fi. 2.0l sohc

 

The main relay is located next to the fuse box under the driver side dash. It a really big relay that has an 8 pin plug.

 

Ya I looked there, thats were it said on the comp. Idk ill look again, maby im just blind or something

 

Make sure the car is at running temp before you try to adjust the idle.

 

Here you go!

ThaThank u bro thats perfect

 

I have the same problem it happens randomly even when the engine is not cold (right after starting), it goes up to 2800-3000 rpms and does not want to come down for a minute maybe more. Same car 89 carburated.

I keep adjusting the idle and throttle cable in small increments to find a "sweet spot" because when the engine is at idle speed the rpms want to drop low enough to where the engine shakes when I'm not moving (in D or R with foot on brake) this makes me throw it into P or N at a stop, the rpms raise about 200 rpms thus engine doesn't shake or hesitate.

I'm not sure if it is a problem other than idle adjustment but for some reason it does bother me and I'd like to find out how to fix or tweak it. Other than that the car runs pretty good being 20+ years old.

 

I had to constantly replace the carb on my 88 accord as it kept giving me idle and stumble issues after so many miles. When it had a new carb it ran awesome.

 

You should go to 3geez.com for more info. I wish I could help you but I don't know anything on carb models.
