1) Check for voltage at injector clip 1.

2) Check for spark at plug 1.

3) Compression test the cylinders.

Well you keep cranking until you get the highest reading. 3 things cause misfire comp, spark, fuel. You can get the two wires with light bulb and plug it in the 1st cyl injector clip and see if its flashes. I think your comp is good. Its prob spark.

 

This is the correct way to do a compression test. If you did the test correctly, then cylinders 1 and 4 have low compression.

Again, if you did the compression test correctly, cyls 1 and 4 are low.

 

if it flashes its getting a signal, its good there. Check if you have a right firing order. I heard before that cat might cause it, but i never had that prob so i dont know the symptoms.
