Engine Performance problem
1994 Acura Integra 4 cyl Two Wheel Drive Automatic 154000 miles
----------------------------------------------------------------
My car speed drops when i'm driving for about 30 minutes and after that is ok. It happen when i'm driving about 65 mph or less. I have my foot still to the gas pedal. Speed drops, then i depress the pedal more to gain speed back.

In the past year I have changed spk plugs, ig coil, fuel filter,and spk plug cables.

Hi adix2,

Unless you are driving on level roads without any gradients would you be able to maintain the same speed with the same throttle opening.

I don't see any problem that you have unless the drop in speed is substancial and you are not climbing up a gradient.
