My car jerks around 1500 rpm at low speeds. I hear some misfires while idling. Are both related?

Pre 2002 Vtecs do have the 'jerking at low speeds' problem but idling should be steady. Misfiring can happen when the fuel wouldnt flow freely in my non-expert opinion.:)

Mine is a 1.5 non-VTEC model.

When were the injectors cleaned last?

Almost 2years back. When I retard the ignition timing the misfires disappear and the jerking too but no pickup below 2k rpm.

If you are mucking about with the distributor, you are changing the base timing which is not a very smart move (unless you are compensating for the same by changing the ECU's ignition maps, which I don't believe you are doing). The ECU expects the distributor to be timed in such a way as to get 12 degrees BTDC when the service connector is jumped/shorted.

At no point should the distributor be used to "advance" or "retard" timing as you are throwing off ECU calculations. If your mechanic has taught you this skill, please go and slap him twice; once for teaching you something which you don't completely understand, and once from me.

Yes my mechanic told me that to increase pickup advance the timing. So now how do I set the timing correctly.

Go to authorized service station and ask to re adjust the settings to factory default.

Okay will go to honda service station to reset the timing and adjust the tappets. Will setting these two get rid of the jerking problem? Also I am running with the improper timing from the last 1yr. Has my engine got some damage due to it?

My City recently had a serious shunt.

Although most of the damage is to the right front fender, I am afraid my front bumper which was literally hanging on by a thread (Steel wire to be exact ) is no more usable.

I had been putting off changing the bumpers for quite some time. But now it seems I don't have a choice.

Anyone have any leads on where I can find a set of new bumpers from my OHC in Bangalore.

I dont mind a custom set also as long is the quality is good/great.

Check the place I have pointed out with an arrow. Where the distributor touches the head. There should be a notch made from the factory across the distributor and the mounting pillar on the head. A semi-reliable way of fixing the issue would be to loosen the 3 bolts that hold the distributor and turning the distributor so that the notch forms a single line across the two. Then tighten the 3 bolts.

The correct/scientific way to get the correct base timing requires a timing light. If you're getting the timing fixed by the dealership, ask them to use a timing light; should take no more than 3 minutes.

Jump the service connector, start the car. Check Engine Light will come on. Let it idle, no revving. Assuming the timing light has been connected at all the correct places (battery terminals, spark plug #1), the light will strobe when #1 cylinder is fired. Point the timing light at the crankshaft pulley and look through the 'V' notch in the timing cover. The light, notch and pulley should coincide in such a way as to get the middle timing mark from the 3 (10, 12, 14 degrees) when the light is strobed; which is 12 degrees BTDC. If incorrect, adjust the distributor (advance/retard) until it does.

Thank you very much pranav. I am out of station so gonna fix the timing by the semi reliable method. If the engine feels better I would get it done from HASS in front of me to ensure they use a timing light and set it to 12 degrees BTDC.

If you do manage to get this done at a Honda service center, please do share the details of which one, where and how much they charged for it.

Also most importantly, let us know if they let you be present personally when attending to you car. Some of the bigger Honda ASS centers are notorious for their less than honest service experience

Most probably that will sort the problem.
For misfire there are many reason out of which one or more may possibly be there i.e. vacuum leak, valve not seated properly, distributor coil, plugs, plug wires to specify few. So you need to get it diagnosed.
When was the last time you replaced your timing and was timing set during that replacement? If you continue with that may cause permanent damages.
So go to a competent workshop (not necessarily expensive) as soon as possible.

@Vandit, I will surely let you know about my experience at the HASS.

@Honda Monk, timing belt was replaced recently. Also after replacing the timing belt I hear some noise when I start the car first time. Later the sound disappears. After that a whirring noise comes everything I rev the car.
