Question about Acura RL

1 Answer

I have changed the egr valve on the acura 96 rl it is driving much better, at first the check engine came on and i notice when i came to a start it would delay when accelerating or if stopped would seem like it would miss, after changing the egr valve it doesnt miss when in idle, however, every now and again while driving will delay very shortly when pressing pedal to start moving then the check engine came on and the code 0401 came up again egr insufficient flow what else can i do i check the small hose going to the egr it is clean?

Possibly problem with the catalytic converter beginning to clog up and restrict exhaust flow but I don't see how that would directly affect EGR sensor. Well good luck with it

Check engine light has 5 codes, p1491, p1201, p1202, p1203, p1300

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?,carcode,1000966,parttype,10767 1996 ACURA RL Ignition Misfire Sensor 19100674-o5bk0cq15nzcjcdo4dxi1a1k-2-0.jpg <<<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.

I replaced EGR valve on my 97 Acura 3.0 CL after

I am fixing to change my EGR valve and the piece of paper that came with the part say this:

Important Notice
Before installing this part, check the EGR valve passage in the intake manifold and clear any carbon blockage. Failure to do so will result in repeat malfuntion of the EGR valve system. Refer to a technical service manual or contact a service dealer for proper cleaning procedures.

Hope this helps.

My check engine lights stays on

Hi, the best thing at at his point is to get a diagnostic review by using a diagnostic computer at the local dealership or garage. Once your car has been diagnosed, you will be able to reset the cpu and the light will go off. its probably just an O2 sensor or egr valve needed.

Low flow Egr check engine light

You need to pull your plenum and more than likely the intake and clean out the vaccum port in the intake where the egr pipe connects to the back of the intake.Not sure if you can do it with just pulling the plennum or not though.Having the same prob with my 96 rl.Keeps kicking the insufficient flow to egr valve code at about 30 miles.
