Well I hav the same problem too. On 1 & 3. I went thru all the motions with it. Coil, MAF, Plugs, and wires. The I pulled the the wires and checked for spark. And YEP. I had spark.
So I changed the oil and filter hopin it was that. It wasn't. But I need it too. Putterin bad. So I know I was drivin on 2 cylinders.
So I plugged the injector connector to see if it would show signs. Yeap, just what I figured. Both 1 & 3 injectors not firing.
My question is. Why does it seem to happen on one side? Thats what crazy too me. I see it alot. Is there a fuse for the injectors?
