P0353 CHEVROLET Description
The ignition system on the vehicle uses individual ignition coils for each cylinder. The Powertrain Control Module (PCM) controls each ignition coil operation. The PCM
sends a ON/OFF signal to energize the ignition coil to create a spark
at the spark plug when a spark is required at the cylinder.
first, test for spark at the ignition coil. take the power cable that connects from the ignition coil and disconnect the end at the distributor. hold the bare connecting end a fraction of an inch away from a metal paqrt of the cars frame and attempt to start. if the ignition coil is good, it should throw a spark. if the ignition coil sparks, next check your spark plugs for oil, grime, black or white discoloration on the spark tips (that point inside the engine). if there is a lot of build up or discoloration, replace the spark plugs. if this does not solve it, change your distributor cap, and if this doesnt slove it, change your spark plug wires.
could be the ignition coil (you can check for a spark on the ignition coil by holding the power cable coming out of the ignition coil close to an unpainted metal part of the frame. if the ignition coil has spark, then change your spark plugs (if the tips look burnt, crusty or oily), spark plug wires and distributor/coil packs.
1.1. Front cylinder bank spark plugs removal: 1.1.1. Disconnect the battery from car terminals. 1.1.2. Remove the engine plastic cover. 1.1.3. Disconnect the ignition coils electrical supply cable and all three coils connectors. 1.1.4. Remove all three ignition coils screws. 1.1.5. Remove all three ignition coils out from cylinder head. 1.1.6. Remove all three spark plugs out from cylinder head (straight forward).
1.2. Back cylinder head bank spark plugs removal: 1.2.1. Remove the inlet manifold out from cylinder head. 1.2.2. Disconnect all three ignition coils connectors. 1.2.3. Remove all three ignition coils screws. 1.2.4. Remove all three ignition coils out from cylinder head. 1.2.5. Remove all three spark plugs out from cylinder head (straight forward).
My 2004 Verona had factory installed "NGK BKUR6ETB" regular spark plugs which I replaced at 30,000 miles. The 2005 model year is supposed to have Iridium spark plugs. To replace the spark plugs: 1. Remove plastic top engine cover. 5 nuts 10mm socket. 2. Unplug connector from each ignition coil. qty 6. 3. remove 2 hold down bolts per ignition coil. 10mm socket. 4. remove ignition coil, lifting straight up. 5. Spark plug is now accessible, use deep well 5/8 spark plug socket to remove.
