Honda Civic DX 1990
I changed an used distributor about two years ago. I have a one-month new
clutch and all my valves are adjusted. My water pump and timing belt are
about two years. My car ran smoothly for the first week after adjusting the
valves, but the same old problem occur after that. The problem is that when
I press on the gas pedal unexpectedly, it does not accelerate immediatelly.
Some times it does not even accelerate. The engine is reving, but no
acceleration. I took to so many mechanic, but no one knows what causes it.
Any one has similar problem, please share. Thank you.

The new clutch needs to be adjusted, now that it's 'broken in a bit'.
If engine revs up, but no increase of ground speed, clutch is slipping.

If engine runs weak, timing belt is out a notch.

I forgot to mention that it also happen with the old clutch. This is the
first time I changed my clutch. So, would the problem occurs in the first
clutch?

Hi,
Sounds like timing issue.
Is there any vacuum leak in the intake manifold?

Interesting issue. I'll check that for sure. Any more possibilty? Thanks

 

check the tandem valve is operating properly. if you take off the top
off the throttle body, you can see it operating like a choke - it should
open when you open the throttle.

there's a piece of vacuum hose that runs from the tandem control valve
[at the bottom of the throttle body] to the tandem diaphragm. if this
is cracked & leaking, you'll have exactly the problems you describe
because the tandem is not opening fast enough and the valve is choking
off air supply to the engine during acceleration.

These are great possibilities. I'll check it tomorrow and let you guys
know. Please let me know more if there are other possibilities. Thanks
all.
