I used my code reader, it comes up P0171-system too lean and pending code P0170-fuel trim malfuction. Where do I start to remedy this problem. I just got this car and need to pass emissions and safety testing, but can't witht light on. Can you help me?

Hi a1tinter

When fuel trim is too lean, you need to check for
1. Vacumn leakage at manifold.
2. Clogged furl filter.
3. Faulty O2 sensor
