my acura revs up and down when i first start it. it does not do this everyday. then when i put it in drive there is a very big kick. any suggestions as to what the problem may be?

Clogged fuel injectors. I would run a batch of injector cleaner through it and see if it helps. If not, no harm done and you are only out a couple of bucks.

Check the coolant level (and purge air out of the cooling system as described in the factory manual). If this doesn't fix the trouble look towards the coolant temperature sensor. If it is defective it can make the engine rise up and down when cold and then stop once it warms up. Hondas and MItsubishi's are prone to this as well. This is not the only possible cause of this of course, but if it only does it when cold then would definitely check. I had a Honda do this (parent company of Acura as you know) after installing a new timing belt and water pump and had forgotten to purge the air out of the system when refilling. Fixed it right up and have since found that problem with the others mentioned including my own 90 Eclipse.

I have the same issue with my integra... i have replaced the MAP sensor, IAC Valve, checked for vacuum leaks by two different mechanics and just like the above it doesnt do it all the time but mainly when it is cold... I know it isnt the transmission and like my v4 (if i wanted a jet i would save for one) but i have been given ideas about the O2 sensor, EGR Valve, TPS and also the automatic choke?? Anyone have some rather intelligent thoughts on this?

Try a can of fuel injector cleaner. Run one tank of high octane gasoline through it also. I had a car that did that once, I would sit and wait 30 seconds, then kick the accelerator it would idle down immediately. I do not mean riv it up, just kick it once to idle down.

The throttle actuator will create an increase and decrease in the engine.You should have your car diagnosed by a licensed garage.It will save you a lot of headaches and money.

if it does only whemn it is cold "when then engine has not been started for a while" you could have a vacuum leak or even possible that the throttle cable is too tight. also check your coolant level.it might be low.

its your idle air control valve located in the back of the intake mani you might not need to replace it but just adjust it with a hex key....

Your transmission is going bad, try to put in transmission treatment, also check your engine mountings.
