Hello All First post.

I have an issue which is now unbearable anymore and cannot find answers.

I have a Civic 97 EX 4D sedan.

On some days its a good boy and others very bad.

When I accelerate (pressing on gas) is feels like someone is pressing on the break, much like a instructor car when the instructor assist you when in class.

what I have to do is tap the gas like shifting in manual, and it goes on for a few min. If I feel this sensation, I pull over and stop my civic will feeling like rumbling, going to stall then its fine.

I have already changed the fuel filter, changed the sparks. Friends suggested the the cables need to be changed or get a full transmission fluid flush or maybe the onboard computer module...

Anyone know?

 

Have you tried cleaning your IAC sensor?
That problem is normally revving up and down.

Is you car Automatic?
-B

 

Sounds like a plugged catalytic converter to me. Does it still have it's original exhaust?

I'd check the distributor cap and rotor as well.

I highly doubt it's the ecu or tranny fluid.

Can you better describe this "sensation" you felt?

 

I agree, could be an exhaust problem.

I have my Cat fall apart inside. Lost all power, and wouldn't make an power about 3000rpms...

 

Yes my civic 97 is an automatic and everything is original, no rust just a great car.

Let me in detail describe it again:

I give gas...... its slowly decreases power even with foot on gas, goes to a certain level of slowlness then "BAM" I get all this power saved up and go like a rocket.

When I get this feeling I usually stop on the right and brake, my car will rumble/shake/stalling then very quiet/smooth then everything is fine for 1/2 a day.

Some days its like nothing happen, some days constant.

To overcome this I just give gas, when I feel declining I let go of foot and again apply gas..... I think my civic guzzles gas like no tmr.

 

Would have to say the distributor. Its missing or retarding the timing.
