Acura 3 5RL Trouble Code Info Basically your whole engine is misfiring. BUT!! IS it running rough? What is it doing? I would replace your spark plugs first and check the gap. Clean your EGR valve and the hose running to it. One of those codes is about your EGR valve. Check out the first link I posted in this to see what your codes mean. If this doesn't fix it, you may have a coil problem . You can pick those up at a junk yard pretty cheaply. When you check the coils, make sure there is no gap in the stick. Half way up you will see a small skinny seam. It should be almost imperceptible if they are good. Also, there is this handy dandy sensor: Called a Ignition Misfire Sensor. I wonder if yours is bad?http://www.rockauto.com/catalog/x,carcode,1000966,parttype,10767 1996 ACURA RL Ignition Misfire Sensor <<<these are coils. Half way up the stick you may see that seam I was telling you about. So, make sure you get the tightest gap you can if you go that route.

IT is a "Time for Service Code" B2 Means its time for an oil change, Tire rotation, Cabin filter replacement and air filter replacements. Call your dealer or local Acura rep for an appointment. Hope this helps.

go to an acura dealer with the vin#.

You need to get the serial number off the sticker attached to the radio. It will require pulling apart your dash. Call an Acura dealership with that serial number and they should be able to provide you the code.

you need a radio code which is a 5 digit code usually place in with your car/owners info booklet. if it is not there you will have to bring it to a acura dealership ..there is a way that they can retieve the code by finding the serial number of the radio , punching it into there system and accessing the code.

Go to the Acura dealer that originally sold the car and they may have the code stored in their system. If not go here http://owners.acura.com/ and sign up and register your car. There with the VIN # and radio serial # you can get the code.

Look in all the paperwork for the code. If that does not pan out, contact the dealer that originally sold this car as they may have the code stored on their computer system. Lastly.Go here: http://owners.acura.com/ Register your Acura and the follow the directions to acquire the radio code from Acura.

Call an Acura dealership with that serial number and they should be able to provide you the code.

you have to call the dealer...i killed my moms battery in her honda pilot. she had to call the dealer. luckily my RL had the code written in the handbook. but you usually have to go to the dealership.
