A few weeks ago my CEL came on without me doing anything specific, I checked the codes and got p2190 and p2188. I googled a little bit and started to look into my MAF:s, they seemed fine but I’m not sure. Also, my air filters and air filter boxes were clean and seated properly and I couldn’t find or hear any air leaks and so on.
I have since then had to clear the CEL every now and then because it keeps coming back with the same codes. So the problem is not solved.

The car seems to run fine, steady idle, doesn’t seem to have power loss and it sounds like it always have.

I’m looking for anyone that has any experience about this specific problem and what it could might be and of course how to solve it. Because I’m not really ready yet to get ripped off at a dealer.

The car’s mileage is around 160.000 kilometres and it has been serviced properly since it was delivered.
Never winter driven but it has been driven below freezing a few times.

Check your intake manifold gasket. Spray some carb choke cleaner around where the intake manifold meets the head. If the idle stumbles you have a leak. If you do replace your Pcv valve at the same time since the manifold has to come off much easier job.
