Emission Problems
A couple of days ago I noticed my 1996 Explorer (V6) was idling ruff, she runs fine though...or at least I belive so. Later my check engine light comes on, I pulled code P0401 (EGR flow insufficient) from the ODBII and cleared it. Next day the light came back on, pulled codes P0455 (Evap emission cont sys leak), P0401, P0171 (sys too lean-bank 1) and P0174 (sys too lean-bank2). Was able to clear the codes again and so far the light has not appeared again, but knowing something is wrong. Any recommendations on where I could start? This is my only vehicle and I would like to do the work myself instead of taking it to a shop
