So this morning I get up and change my oil to 6quarts with a fram filter. Drove it for about 10 miles then the service engine light came on. So i pulled over checked my oil and everthing looked fine. I got home and disconnect my battery and it work but after 5 mile the light came back on. Now ive had a prochamber for about 1 month with the O2 sims and never had a problem till today. What could of happend? I didnt touch anything else. Im afraid to take it to ford and it was so hard to get the pipe on and i dont want to pay the same guy 80 to put the stock back on just to have ford look at it. I bought the O2 sims at Rpmoutlet. Please help Im so mad i only got 9000 miles on the car.
