So a friend ran my smog numbers and said I was running lean. So I tested the psi after the filter and came up somewhere between 10 and 11. I think normal is 9-13 correct? If it is normal, should I try the o2 sensor next? I just put a new one in last year, and don't even have 200 miles on it yet (unfortunately I bought it at vatozone, so it might not even work.
