What else could be making my 2002 VW Jettas check engine light pop on?
The code is always Bank 1 TOO LEAN. I’ve had it to the dealer twice. First time they changed the mass air flow meter and spark plugs. They also cleaned the fuel system. Second time they said everything related to the fault code was performing within specs and basically told me to come back when I had a real problem. Just wondering if anyone knows what else this could be? Already checked for vac leaks and there are none present. And fuel pressure is fine. A: if they fixed it the light will go off, simple as that. what they didn;t do that you paid for them to do was fix it, which means the light off and codes not popping up in the system.
