Question about 1986 Honda Accord

1 Answer

!986 Honda Accord revs on its own

When i turn on my car while it's in "P" it goes up to 1.5 - 2rpm. I adjusted the Idle Adjusting Screw but so far still the same. It also occasionally does the same when stopped like at a red light for instance. Is it most likely the throttle position sensor or is there other things i can try out before i go out and spend money??

Idle adjustment problem


If the idle mixture screw ( idle screw) does not make a difference it is because the idle circuit is blocked . Check the jets for dirt / water . Blow out the system with compressed air.. The mixture is already set by the time it gets to the screw and you are only increasing or decreasing the volume allowed into the engine . There will be no "O" ring but there should be a spring under the head of the screw.

How to Adjust idle RPM for a 2003 honda accord. some people were talking about a screw on the throttle body. but I can't find that screw. How do you go with adjusting this and where to find it ?


First, you shouldn't adjust the idle. If the idle isn't correct, that means there is an issue somewhere - not that the idle needs to be adjusted.

There isn't an adjustment screw. To adjust the idle, you will need to move the TPS (Throttle Position Sensor) forwards or backward. To do this, you will need to remove the tamper proof bolt and replace it with one that can be loosened and tightened.

How to Adjust idle RPM for a 2003 honda accord. some people were talking about a screw on the throttle body. but I can't find that screw. How do you go with adjusting this and where to find it ?


There isn't an adjustment screw that you really manipulate. The computer dynamically controls the throttle using the information it gets from the throttle positioning sensor (TPS) on the throttle body. The TPS is secured with tamper proof bolts that the head breaks off when torqued down. If you remove the throttle body and extract those bolts, then you can add bolts/screws with head and can be loosened and tightened. Then you can move the TPS back and forth to adjust the idle.

I wouldn't recommend doing this though: if there is and issue with the idle, it is because something is malfunctioning, not because it needs to be adjusted.

How do you idle up a 1991 honda accord


Look for a screw or nut that turns.Look at the cable that is connected to your accelerator.You can push back on the throttle and hear the engine race.The adjusting screw should be there.A few things to note....Wait until the engine has warmed up and the choke off..check the auto choke is working before you play with the idle...replace the air filter...by increasing the idle the Engine will be running"richer" before you adjust anything I would invest in a complete tune-up.The above info is for all carburator engines only.Good Luck.

1989 accord lx, idles high at start-up, now it won't stay running


Carburated engines of that year may have an idle screw adjuster. You can see the screw from the outside of the carb. If so, try adjusting the carburator with a screwdriver. Unlike fuel injected Engines they can be manually adjusted.

Car stalls when i stop


it sounds like a low idle either caused by poor adjustment or a dirty throttle body. clean the carbon out of the throttle body. if that does not work bring the revs up with the idle screw

Should be an idle adjusting screw on the side of the carburator that you can adjust to move your idle down.

I have a 1987 honda accord lxi i took it to the shop and when i got it back they told me i needed a new idle adjusting screw and that they put a temporary fix in the car now my car is sputtering and not...


im sorry to say that the idle screw wont fix your problem,that just keeps the idle at the right rpms. could be bad plug wires or anything please take to a different shop.
