Hi guys, ive had the CEL on for around 2 month and the car was still running normal. my scanner was reading the code P0171 system too lean. So 2 days ago i took it to the dealership to get it fixed. they told me its the o2 sensor and they did replace it. they took it for a road test and 5 mins later the light came back on. Now theyre telling me theres something wrong with my stage 2 kit...? i dont know what to do. have anyone had a similar problem before? i really doubt theres something wrong with the stage 2 kit. but who know.. anyways, any thoughts of what the problem could be?
thanks.
thanks.
