Does it happen when you step on the brake or when you are already moving?

It happens when I'm already moving & sometimes even after I press the brakes all the way down, as soon as I take my foot off it accelerates right back up without me even toughing the gas pedal.


Sounds like the cruise control is activating on it's own. Try disconnecting the cruise control servo motor in the engine compartment, if that cures the problem then the cruise system will have to be checked out, could be bad switches sending a turn on signal all of the time.

Thank you! I will try that & hopefully it works!

Well I think we got the cruise control completely disconnected, but it is still doing the unintended sudden acceleration and it seems like it has only gotten worse! :/


Then you are going to have to dig into the computer control system. As this is not an OBD 2 system you may have to call around to find a shop that check it out.


There have been numerous complaints about Acuras and sudden acceleration. I'd check the VIN to see if any TSBs and recalls have been issued: http://www.aboutautomobile.com/TSB ; http://www.safercar.gov/Vehicle+Owners ; http://www.autosafety.org/category/categories/recalls/check-your-vehicle%E2%80%99s-vin-outstanding-recalls ; ----- with the Acura, is seems the acceleration is affected by a sensor, but what and where you might need to research further.


Sure its the iac bro...
