Step daughter has a 1989 honda city , hesitates at

Step daughter has a 1989 honda city with the 12d engine and a carb , hesitates at intersections and stalls ,
it haS A slight miss till about 5000 revs ,at about 3000 when driving up road you can feel it surging , is more previlent when engine gets warm and seemed worst when raining? . often it stalls as you are coming off a roundabout . The float adjustment screw speaped a bit of petrol so i chucked some stuff in recess to stop that . but not sure if letting to much gas in bowl would cause problem float seemed to be set to high, can't find obvisous vaccum leak gonna try a bit of ether tomorrow. looks like some one had done some work to carb before with new lookin gaskets but the previous owner said it had problem for a while hmmm. anyway any ideas ta james

This is what id do...

Id remove all the spark plugs and inspect them.
This is how i diagnose fuel/spark suspect issues.
Buy doing this you will be killing two birds with one stone.

1.See if the plugs have been firing correctly.
2.Are the plugs fowled or are they running to lean?

If your fuel/air mixture is too lean it will not ignite properly on the power stroke. So it may miss one power stroke until the next power stroke comes along which would add more fuel and then ignite.

Something like this will be causing that funky stuttering missing that you have described above...

And id say if it comes right over 5000RPM thats probably because the carb your running is a two barrel or similar and the second butterfly will open roughly about then and be providing that extra mixture.

I encourage you do just do a bit of investigating you will eventually find your problem.
I wouldn't go buying random parts and just throwing them on until you no what actually needs fixing other wise its just a stab in the dark...

Hope this helps let us no how you get on...

Try the coil pack... pull a spark wire at a time... note any change in how the motor runs ? ... plug it back in and move on to the next one

1989 jeep wrangler, motorcraft 2100 upgrade(carb), runs VERY bad, hesitates upon acceleration etc..ran like the before the new carb only not as bad. What could the problem be?


If you barely push the throttle and it's sputters, try unplugging the EGR valve and see how it runs.Make sure you have vacuum to the EGR valve.Start engine and on the outside see if you can put your finger under the EGR valve and see if it sucks up. Be careful and not let the engine get to hot when you do this test.

My honda crx is starting over but won't idol properly and will stay on for a few seconds before dying. i checked to make sure gas is getting to the engine and it is.


I have same car 1989 honda crx, what worked for car was I took the Idle Air Control Valve ( IACV ) off and cleaned it with carb cleaner. What you will need is a 12mm socket and only has two screws, and pliers to take off two small hoses attached to it.. And most important carb cleaner to clean the inside of IAVC. Plus you can also search for this on the Internet ...1989 honda crx Idle Surges! Hope this helps...

2003 honda fit intermittent hesitation


@ aroyb - A timing light are you kidding? This vehicle has solid state distributor(no cap and rotor). It has computer controlled ingition and engine timing so a timing light is useless.

Carb diagram honda 1978


Sorry, your question is way too vague and confused. You did not mention model or engine size. You also did not mention whether you are talking about a car, a motorcycle, or even a generator....Honda make all of those. Not to mention, your question somehow got posted under the heading of 1989 Volkswagen GTI....So are we talking about a Honda or a Volkswagen? There is no way anyone can get you what you are asking for because it is very unclear what it is.

1989 Honda Accord Dx which Idles @ about 4250 rpm for about 5 minutes and then shuts off completely unles at this point I'm pressing the accelerator.


sounds like the idle air screw needs adjusted out on the carb, to slow the engine.. did you just get the vehicle, and trying to fix it up, or is this something that just happened??

Just installed new carb in my 1989 honda. Used diagram to connect vacuum hoses back up, but car idle speed is too high - up to 2,000rpm. What could be wrong?


try turning down the idle via the idle adjust set screw (usually on the carburetor base). if the problem persists after the engine is warmed up, there may be an issue with the automatic choke. also check the throttle linkage by disconnecting it to see if it is holding the throttle open when connected. if this is the case, you may need to adjust it or find a slightly longer cable.
