Engine Performance problem
1989 Honda Civic 4 cyl Front Wheel Drive Manual
----------------------------------------------------------------
The car developed this problem about 6weeks ago. The engine could not fire very well, i took it to my local mechanic, he change the injector nozzle and yet the problem is still on. He decided to clean and service the injector which he did but yet the problem is still their. What i observe is that the engine start normally and work well, but when you press the accelerator it will not fire properly and if you do that continuously the engine will stop. I have change the spark plug but no improvement. kindly help.

Hi chrisletua,

Did the Malfunction Indicator Light show?

Did you test the fuel pressure ?

Are sparks strong (bluish in color)?

About the malfunction indicator light - the light did not show

For the fuel pressure - the pressure is ok

But for the spark plugs - i don't how to check that. but what i notice now is the cold starting. If that is as a result of the plug. what type do i use.

Thanks for your assistance.

Hi chrisletua,

Pull a plug wire out and attach a spark plug. Crank and watch the color of the spark, should be builsh.

I have check it and it is ok. can you please tell me the type of spark plug that my model use. Because, when i look at the plugs their, my local mechanics mix diffrent type.

Thanks

Hi chrisletua,

Should be NGK BKR6E-11. I need to know the engine variant to be sure.

Hi Mr. KHLow2008, Moderator
Thanks so much, you always stand by me. I have search for the spark plug NGK BKR6E-11, but i cloud not find such, what i find is NKG BKR6E. the only different is the last 11.
I dont know if its the same type.

Now the car is given me a grounding sound like one bearing is bad some where. I suspect the rear Tyre side. But if i checke the ream on the tyre (the 4 tyres)no of them is hot.

secondly, the gass consumption is too much.
Please what can i do.
Thanks

Hi chrisletua,

We would always have our arms opened to welcome you anytime.

NGK BKR6E would have a gap of 0.8 mm whereas the 11 = 1.1 mm. You can use the plug but they have to be regapped.

A smaller gap would cause higher fuel consumption.

Where the gas consumption is concerned, it would be hard to advise or suggest anything.

Possible causes.
1. Engine ignition timing.
2. Idle speed adjustment.
3. Driving method.
4. Brakes.
5, Clutches, might be worn and slipping causing power losses too.
