Question about Cars & Trucks
Posted by Anonymous on
Code po305 is # 5 cylinder misfire. Check the spark plug wire and spark plug. use an inline spark tester to check the wire from coil to spark plug. If you have spark,then remove plug to see if it is fouled out. the best time to check for brake or cracked spark plug wiring is at night with engine running and doing a walk around to see if the insulation on wireing is broken or cracked. you will see the wires sparking at night. then replace the wires that are causing the problem.
