I own a '95 Honda Accord 4cyl with 123,000 miles and last month got a new timing belt & water pump from a reputable shop. Since then, and now getting worse either cold or hot, when accelerating from idle-to-45mph and beyond, the engine is revving up and down randomly with no obvious connection with the transmission (which has had no problems) gearing up and down which remains as smooth as it ever was at all speeds. While drivable for now, even the slightest acceleration will randomly trigger the revving with no other obvious audible issues. However, there is another repair issue where the A/C is dripping condensation on the carpet under the glove box. Are these issues related?

Vehicle is a 1995 - not a 1999.

Is the Check Engine Light indicating?

Check the coolant level in radiator. Insufficient coolant would cause the Idle Air Control valve to malfunction.

Check the A/C condensation water drip hose to see if it is dislodged.

Thank you for your response! No check engine light issue. However, the revving seems minimized (but still present) when the a/c is off. Vehicle has been very reliable with little engine repairs other than the timing belt/water pump replacement about a month ago.

Have you checked the coolant level in radiator?

Did problem occur after replacement of the timing belt and water pump?

If idling speed is too high, it can cause the problem as well.
