02 d2 se7 163,000 miles, daily driver.
I recently had this code p0150 come up. I bought a set of 4 "el cheapo" o2's and they gave me 4 new codes, from reading threads on here I gathered that the "el cheapo's" had to go back.I returned them and got the Bosch from Amazon, just one due to finances. I put the old o2's back in and I'm back to just the original code. Today I used a code reader that's more advanced than what I own. I took photos of the o2 monitor and I honestly don't know what I'm looking at lol. I can obiviously see there is something wrong, I just don't know how to interpret the data. Any help would be helpful. Thanks.
