I think you're using different words for the same plan. I see only one module/coil pack that covers all 4 plugs. (Item #1) The other items pictured are the ECM and various sensors.I was told my #3 cylinder was misfiring and need to replace the "module" and 4 spark plugs. Instead of replacing one "module" could I just replace all 4 plugs and the coil pack?
They want $176.57 to remove and replace your spark plugs. Highway robbery. You can get a set of plugs for about $30-$35 (MSRP) and replace them yourself in less than half an hour. Not sure that the J4345 part is - that's not the part number for the Cruze's ignition coil rail, which runs around $130 MSRP and can be had for $80 on Amazon. The labor for replacing this part is "free" if you're replacing the spark plugs as it has to be removed to get to the spark plugs.opcode J4345 Ignition coil 400.11$
opcode MSPR4P Spark Plugs, r&r 176.57
opcode Fuel Induction Flush 189.12
So the local chevy dealer wants roughly 780 in parts and they want 790.64 in labor so a total of 15/1600$ for a coil replacement.
I have found matching coil packs online for 120ish and spark plugs for 45ish and a fuel induction cleaning kit for 30$.Should I do this myself for about 200$?
Reading the warranty, it seems unclear.I thought the coil pack was covered under the Powertrain warranty. The spark plugs aren't.
HiIt has under 50k miles. I ordered spark plugs and the coil pack so in a few days I will post on the results. I am highly confident that this will fix my problem. I will be so relived
Usually both, if the fault has been there for quite a while a damaged coil pack would wear out the plug as well.Hi
did the problem fix after replacing the coil pack and spark plugs ? i am getting the P0303 cylinder 3 fault code on my cruze too. i have been told to replace the coil pack. I am just confused on whether i should just change the plugs or coil & plugs.
