My 2001 Cl Type S Automatic has a power drop out when it warms up!

Start the car and drive no problem. As far as I can tell (watching temperature on OBD2 app) when temperature hits operating temperature the motor drops power/RPM (down and back. a half second estimate)then comes back up and no more issues! Any ideas?

Also, when letting off gas at cruising speed, there is an abrupt hard stumble. Not all the time.

I changes temperature sensor, checked all vacuum lines. The car runs great other then that.

Any ideas?

Thanks

 

I'm having the same issue with my 2002 Acura CL type S ,I start the car ,starts up fine,I let it idle not even a minute and the rpm starts feeling like the engine wants to shut down like a misfire feeling but I would shut the car off and start it again and fine? When this issue happens when I'm driving I can go passed 30hpr and the engine sputters... So I shut it down and turn it back on and fine? Need help too but when car is warm no issue only when cold start and idles.....sucks!!!!!!

 

I I just checked online for the symptoms and idle air control valve that's on the bottom of the throttle body if that goes out that could be one of our symptoms but will give no code.... Try opening the idle air control valve and cleaning it with carbon cleaner if it doesn't work then buy a new one I'm going to try this after work
