I got an 02 with a 2.3 with only one coil pack.. trying to figure out the correct firing order. The ones I found here show two coils and this truck dont have that.

I just put an engine in it and I got two coils marked differently. Runs like crap at idle with either one.
It also seems like the front o2 sensor is bad but im not sure that would cause it to idle so rough. Its much smoother above like 1500 RPMS. Gonna run and get an o2 sensor and hope by the time I get back someone will have an answer for me.

The firing order is 1-3-4-2. Get a code scanner and see if you get any codes.
