Engine Performance problem
2001 Lexus IS 300 6 cyl Two Wheel Drive Automatic 120000 miles
i have a 2001 lexus is300 that keeps throwing the check engine light. Po171 and po174 saying that bank 1 and bank 2 are running too lean. When I start the car, it idles at around 1500 rpm. How do I find the vacuum leak?
