Question about 2000 Chevrolet Impala
2003 cheve impala has excess fuel consmption & spark knock. Changed oxygen sensors & plugs, no difference. How do I remedy this situation?
If u do alot of city drivin with short trips try putting some chevron techron in a few tanks of gas(black bottle) and im geussin u use 87 octane,try movin up to 89 octane,try that and also try clening you mass airflow sensor which is on your air intake system for the engine,be careful though..do not bend any of the small wires on the part of the sensor that is in the airflow..they are sensitive,you can buy airflow sensor cleaner at most auto parts stores,hope this helps
