Engine missing while driving

Scan for codes and check fuel pressure with a gauge first. In the USA auto parts rent those.

Dear sir, I have scan too but no codes, no any indication light come into the meter. I went to Honda service center but they also did not found any problem in the car, but car using fuel too much. After running about fifteen to twenty miles it jerks like I feel engine do missing sometimes. A concern to auto mobile person says it is plugs coils (I mean plug cables ) have too much damaged and need to change them. But I think if it is plugs coils have too much damage then how is car running on the roads? Dear sir I am really worry about it. Kindly help me sir or madam what should I do?
Thank you sir.

If you have a ohm meter, check resistance of plug wires should be 5000 ohms per foot if you have wires and it is not coil to plug. Changing plugs should help and what was fuel pressure? We do not have that model in the U.S. but fuel pressure on a Civic is 48-52 psi. So yours should be in that area. Also check vacuum at idle on intake and if 15" or below check for clogged catalytic converter/exhaust. The wire resistance is the same for CNG or gas engines.

My vehicle's engine is missing after I run the air conditioner while parked somewhere or stop for ten to fifteen minutes.
It almost stops after hissing and jerking like there is no fuel.
When I wait for ten to fifteen minutes then it starts and runs.
This problem is only when air conditioner is on.
Recently I changed all four spark plugs and Fuel pump from Honda.

Please advise.

Hi SONIA,

I am wondering if you have a blown head gasket, did all of the old spark plugs look the same?

Please follow this guide to see if the head gasket is blown:

Let me know what you find.

Sir,

My car was giving jerks while running and I sent my car to the service center, they said the A Coils in the Engine are not fine and need to be replaced. I got them checked with another mechanic he advised to get only the spark plugs changed. I did that and the car stopped jerking. I went to the service center again to tell them that their advise was wrong. They checked the car again and again said that the the A Coils are still not fine and the spark circuit is short. Is this possible that the A Coils are not sending current to the engine still there are no jerks while running at lower or higher speeds?
Please advise as I am really confused at this moment, a fast answer would help me a lot as I do not want to get into any long-term problem with my engine.

Thanks a lot.

If it is running fine and no CEL is on with misfire codes I would think things are okay at this time. I am not sure what you mean by avoiding long term problems?

Oh, maybe I misunderstood. Long trip problem is what you meant? They always say, better safe than sorry? Costly little buggers are they not. How many do they want to replace?

Okay, I checked on your year/engine and what you have is a dual spark system which means two plugs/coils per cylinder. That is why the A rating to a coil as in A-B, I am assuming.

Here is the explanation of you system design of two spark plugs: http://www.honda.co.nz/technology/engine/idsi/

I have understood about the engine details and thanks for sending them. But the question remains the same place. What would happen if there is a short circuit in A Coils of the engine, will it still work without any issues or bumps or will start showing some signs while running and what are the long-term issues with this problem?

I am not sure what they mean by short circuit? in the coil itself (all 4 A ?) or in the signal/circuitry? What was their recommendation for a fix?

And apparently the car runs with either two sparks or one and it should not harm anything to do so. It is almost like having a built in backup. The reason they use two is for increased economy.

Car will jerk and misfire during low rpm. I have done throttle body clean up and engine tune up. Also replace all spark plugs and two ignition coils, all the terminal wire's are check and no any problem. But still problem is have. I did not check fuel injectors. And computer is not showing any of error. Please help me.

Check fuel pressure with a gauge auto parts rent it and check for a vacuum leak.

Check fuel pressure and it is perfect. And today we clean fuel injector, but same problem have. But engine check light is appearing now and troubleshooting is oxygen sensor.

I need to know how this sensor failure will effect to engine misfire. Please explain me on this.

Are you sure the fuel pressure is correct? Was it tested with a gauge? Did you check for a vacuum leak? If the engine is running lean the O2 sensor picks that up and you get a misfire because it is running too lean. It also could be a bad fuse or O2 sensor is no good.
