Yes, two filters changed, sorry bout that. I had the codes checked and it had three different code numbers which I did not write down. Standard o2 sensor to lean code, code for bad gas (which I can rule out at this time), and a leak in the manifold which would be I guess, air intake valve or the mass air flow sensor.

I am going to check the connection to the air intake valve and the ma sensor this week-end.

Thanks for your help
