1990 Honda Civic does not accellarete when stopped at light

Hi gmm96b,

You are not very clear about your description so I need more info.

Leaking? You mean the battery is drained of its power?

Check the alternator charging voltage at battery and alternator main mast.

Is the check engine or alternator charging light on?

The catalytic converter is leaking? does the exhaust sound loud? If not, it is external leaking from the engine.

Have you checked the spark plugs? Plug wires?

The old battery was leaking acid (i think) so we replace it with a new one 2 days ago and its started doing the same thing. I noticed because the smell came back and I checked the battery. There is no loud noise, but when i stop at a light or stop sign when its time to go sometimes the car wont move even though i step all the way on the pedal.

Hi gmm96b,

If the leaking is from the battery caps, then it could be overfilling of electrolytes or the alternator is overcharging.

You have not answered my other questions.
I need those to continue.

When accelerator pedal is depress fully, does the engine rev up and car won't move?

When accelerator pedal is depress fully, does the engine rev up ? Yes it revs ups
and car won't move? The car does not move. When i try again it does move very slowly and picks up speed. It does not turn of it will continue running but just stagnant. I hope that answers all the questions. A mechanic looked at it and stated that it was the alternator, i just dropped it off so lets see please let me know if it could be anything else causing this. and thanks for your responses.

Hi gmm96b,

When the engine revs up but does not move, it is the trans not working, nothing to do with the alternator for your model.

Check if ATF level is correct.

The alternator is another problem. If the battery is leaking from the caps, then as I mentioned earlier, it should be overcharging of the alternator or overfilled battery fluid.
