I know there are two different spark plugs leading and trailing but are the 4 coils the same of are they different.

 

All 4 are the same. Replace every 30k miles unless you get the $500.00 setup. They last forever.

 

Is there any way to adjust the idle ?

 

The PCM controls the idle via the idle air control valve. Cleaning the throttlebody will usually help.

 

Thanks having an issue with it dieing at a stop light when I idle drops below 1,000 I changed the cols yesterday but haven't got around to the plugs and wires. What else would cause it to die like that

 

Usually low compression due to carbon accumulation on the apex seals. Throw a bottle of Techron in the gas tank once a month and a bit of Marvins mystery oil with every fillup to keep the cylinder temps down due to ethanol.

 

I feel so dumb today. Went out to check everything over and noticed I forgot to plug in the mass airflow sensor connector. Lol runs fine but still need to change the plugs and wires this weekend but at least it doesn't die
