Last summer I started getting my check engine light coming on, then it would go off by the time I would get ready to run it to the shop. I finally got it to the dealership who said it was a small leak (Code: P0171 Running lean - Bank 1) but they couldn't find it. The tech said it was big enough for the car's sensors to pick it up but after they put it through their normal paces (colored smoke etc.) couldn't locate it. Then she was put up for the winter. This summer started with no issues and a few months ago it started again BUT this time anytime I would "Punch it" the light would return, I go get my regular oil change and add my fuel treatment to the system and for months NO Check engine light at all... Yesterday it came back on. Has anyone dealt with this issue before and if so what if anything can I do about it. Trying to get her ready for the drive to Carmel Artomobilia. Thanks family.
