check engine light stays on, codes read po0171 and 131pending. what do i check?
my pickup keeps acting like it wants to die when i drive it. the check engine light stays on and diagnostic codes are saying poo171 and poo134. translates to lean and downstream sensor in bank one. im not so sure what to do, i have had a new fuel pump put in recently. can anyone give me some suggestions?
