Engine Mechanical problem
1996 Dodge Neon 4 cyl Front Wheel Drive Manual
I keep failing smog test its running to rich but the check engine light is coming on, the code PO171. Running to lean. I replaced the upstream oxy sensor but the down stream oxy sensor is not showing any voltage. Today when I drove home from the smog test it was dieing at every stop light but it would start up right of way and ran fine?
have the same problem?
