I have a cel I can’t get rid of in my 2.2 CL. I don’t remember the exact code but when I hooked it up to a diagnostic scanner it said “Insufficient Air Flow”. I bought a new EGR valve and took the intake manifold off and cleaned it, but the code is still there. What else could it be? ---

probably a vacuum line maybe this will help? [http://www.obd-codes.com/trouble\_codes/generic/p0401-insufficient-exhaust-gas-recirculation-flow-egr.php](http://www.obd-codes.com/trouble_codes/generic/p0401-insufficient-exhaust-gas-recirculation-flow-egr.php) ---

Thanks for the link. I’m going to check the vacuum lines again. Hopefully it’s not another sensor. Those damn things are expensive. ---

If you think it might be another sensor, give import auto salvage a call, they should be able to hook you up. They’re in central NC, not sure how far you are from them but they usually have a lot of parts sitting around and they could/would probably even help with diagnosing the problem. ---

a Friend of mine Is having the same problem on his cl, He talked to a hondatech and he said that the intake manifold needs removed and the carbon needs cleaned out, i do not beleive this. is the problem ---

Mercedes will throw a air injection code if the intake/heads become to gummed up with carbon. Never heard of it happening on a Honda/Acura though ---

I took the intake manifold off and cleaned out the carbon, which there wasn’t much of. So far I’ve done that, checked the vacuum lines and replaced the EGR valve and I still have the CEL. Is there any way to get it to pass inspection with this light on? When I hook it up to the scanner it shuts the CEL off for a little while and then it comes back on again. If I shut it off right before it gets inspected it would still have to complete it’s cycle before it could pass inspection anyways, correct?
