My daughters hasa 91 Honda Civic, 16 valve, 4 cyl. Here is the problem: from time to time there is a brief hesitation when she is driving. Everything goes along fine and then the enging will have a noticable hesitation. It does not appear to be tied to tempeture, or length of time the cars has been driven.

There had been a leak in the valve cover gasket so the gaskets and plugs have all been replaced. My first guess was the fuel filter but I know almost nothing about this car so I may be way off base.

Hopefully someone can provide a suggestion as to what the problem may be.

Thanks

A friend of mine had a similar problem, if I remember right he had a bad injector; ever now and then it would not inject the fuel, and it would seem to hesitate for a brief second, and go back to normal... like i said, I believe that was his problem, so you might want to check that out if you have the time.

 

Do you know how to diagnose somethings like that?

 

well probably just pull out the fuel injector and check it? im no genius though and i havent ever had to take them out so you might have to unplug stuff

 

when i had 2 bad injectors i took a volts meter and tested them youll have to find the specs on what it should be but on mine i tested them 2 were the right spec and two went skitzo changed the skitzo ones and it runs great

 

I had a similar problem in my car.....so i replaced the spark plugs and wires and fixed the problem...

 

My 94 Civic is also having a slight hesitation usually in 2nd gear around 3000 to 4000RPM. It either does not happen in other gears or is soslight that it is undetectable.
So far I have replaced the distributor, rotor, wires, and plugs. I have adjusted the idle speed according to the Honda procedure. I have also put 2 cans of injector cleaner through the tank. I do plan to check/adjust the spark timing.
I have seen a lot of suggestions here, but has anyone else with this problem actualy corrected it? If so, how?
Thanks,
TJ
