i also have to the same problem when changing my coil pack i mixed up the spark plug wires leading to the packs and now it's idling rough...pls help

GMC suggests that all spark plugs be replaced every 100,000 miles. When removing spark plugs, always remove one spark plug wire at a time to avoid mixing up the wires

I hope this answers your question

CHANGE SPARK PLUGS.YOU NEED SPARK PLUG 3/8 SOCKET.YOU NEED SHORT AND LONG 3/8 EXTENSIONS.YOU NEED SPARK PLUG BOOT PULLER AND A SPARK PLUG GAUGE SET THE SPARK PLUG GAP.NOW CHANGE 1 SPARK PLUG AT A TIME SO YOU MIX THEM UP GET FIRING ORDER MIX UP CAR BACK FIRE WONT CRANK.ALSO CHANGE PLUG WIRES ALSO.

First get the spark plugs, then get the right swivel socket for the spark plugs and a gapper for the gap of the spark plugs.

Remove the boot, from the first spark plug, and..

Unscrew each spark plug one at a time (making sure not to mix up the spark plug wires) using a ratchet and extension, and the swivel spark plug socket by turning counter clockwise.

Carefully gap each spark plug, if needed, and insert by hand and slowly screw in each spark plug, making sure not to cross thread.

Put the boot back on to each spark plug, making sure that you squeeze down the connector a little bit to ensure a good tight connection.

Remember, replace one spark plug at a time and replace the boot in order to not get the firing order mixed up.

ARE YOU JOKEING???????LOOK IN THE ENGINE ,,YOU WILL SEE MABY 6 OR 4 ,,,WIRES,,,,,, DEPENDS ON TYPE OF CAR YOU HAVE,,,AT ONE SIDE OF EACH WIRE THERE WILL BE A SPARK PLUG,,MAKE SURE YOU ONLY DO ONE WIRE AT A TIME ,,CANT BE MIXED UP ,,THEY HAVE TO BE PUT BACK THE SAME WAY,,,VERY EASY TO DO THIS TRY IT,,,

Firing order 1-3-4-2 clockwise

2.0L SOHC (single overhead cam) AGSF34EE plugs gap 0.054
2.0L DOHC (dual overhead cam) AZFS32FE plugs gap 0.050

The plug numbers are the motordraft numbers

You want to do it? I'm guessing spark plugs? Pull spark plug boots off, its going to be tougher then you think, they are on there pretty good, then with a long 3/8 extension, and a ratchet, and a 5/8s spark plug socket remove the spark plug. Reverse order to put in. Make sure you put anti seeze on the threads when you put them back in, and do not mix up the spark plug wires.

remove the plug wire from the spark plug and replace them one at a time that way you wont get the plug wires mixed up
