Coil pack connection is physical: Coil 1 to Cylinder 1, 2->2, etc.

I am not sure if this is your question, but firing order matches spark to TDC (top dead center) on the power stroke. The design of the crankshaft determines this.

1-3-4-2 is common for most straight 4's. Cylinder 1 is closest to the crank pulley. I believe your coils are 'waste spark' which means it will fire two cylinders at the same time. When the coil fires, one cylinder is on the power stroke and is wanting this spark. The other cylinder is on the exhaust stroke at this time, and thus the spark is 'wasted' on that cylinder. But a cylinder with exhaust gas has high impedance, so most of the energy is delivered to the intended cylinder.

If your question was 'should I just connect 1->1, 2->2, 3->3, 4->4' [ yes!] vs. ' should I try to connect coils following the firing order' [no] then the answer is the first. The trigger wheel determines which coilpack fires when, you just need to hook up the wires number for number.

My 2004 chevy trailblazer is missing badly. Had them read the code for me at auto zone and it said I had a miss fire on the number one cylinder. I changed the plugs and it is still missing badly


Try moving the coil pack from cylinder 1 to another cylinder (swap locations) and see if the same code comes up. If code is different, then coil pack is bad. Other reasons for miss; bad injector, poor compression.
Also, I know you changed plugs already, but always use AC Delco 43-103 plugs on this vehicle.

Number 2 cyclinder miss fire


IF YOU KNOW IT IS MISSFIRE FROM READING CODES, THEN YOU KNOW IT IS ELECTRICAL AND NOT A VACUUM LEAK. THE CHEAPEST THING TO DO IS REPLACE THAT SPARK PLUG AND SEE IF IT HAPPENS AGAIN ON THE SAME CYLINDER. YOU MIGHT WANT TO CHECK THE COMPRESSION ON THAT CYLINDER WHILE YOU HAVE THE PLUG OUT. IF YOU STILL HAVE PROBLEM REPLACE THAT PLUG WIRE. IF IT HAS INDIVIDUAL COIL MOUNTED ON EACH PLUG, THEN TRY SWAPPING FOR ANOTHER COIL ON ANOTHER CYLINDER. ]
THE PLUG-IN CONNECTOR ON THE COIL FOR EACH CYLINDER IS PRONE TO GIVE TROUBLE. CHECK IT CAREFULLY AND MAKE SURE IT FITS TIGHT. IT SHOULD HAVE SOME WATER-PROOF ELECTRICAL GREASE IN THE CONNECTOR.
HOPE THIS HELPS. ROBERT

I have an 2002 buick century that has a iginition miss. We have changed the spark plugs, iginition wires, coil pack. It first came back with a miss fire number 2 cyclinder. The coil pack was changed. Now...


double check plug wires to be sure they go to the right cylinders. After that i would check fuel injectors
You need a listening device and listen for metallic clicking sound. Bad injectors will be silent and they do cause the same miss
