Question about Cars & Trucks
Posted by Anonymous on
Most likely this is a false code being shown due to a faulty Map Sensor or O2 Sensor. Replace the O2 Sensor at the downstream position and double check any exposed wires for damage. I have had this problem in other vehicles, it turned out to be an exposed wire on the Downstream O2 sensor that was grounding causing a problem and a bad O2 Sensor. The MAP sensor will do the same thing on occasion but is less likely.

i would suspect either the coil pack or the leads ,also make sure spark plugs are set to 25 th as too wider gap could cause this problem as well
