No combustion in cylinder 2 and 3

[ateeb786]

I was on the highway driving home from work and I heard this loud pop sound from my car. I had a feeling it was one of my ic hose, I pulled over on the side and sure enough it was the hose that connected between the elbow and the ic pipe. That same day I cleaned out my car so I had no tools with me. I tightened the clamp as best I can but it was still pretty lose, so the car was running crappy. I drove about 8 miles like that on the highway going 35 to 40mph, I couldn't go any faster. I got home and tightened all my clamps. OK NOW I drove it again the same night and it was driving the same way just a little bit better. I did a boost leak test, found a few leaks fixed them all. Did a boost leak test again and it goes up to 20 psi no prob. Changed the spark plugs, made sure all the sensors were connected, oil was fine. STILL rough idle! It was fine when i drove to work. Im stomped, its kind of running like the MAS sensor is not connected. Any help would be very very appreciated.

Also Me and my friend did a few tests, this is what I got. The 2nd and 3rd cylinder are not having combustion, we took the spark plugs out and those two were filled with gas. The 2nd was 180, 3rd one was 170 so the compression was good. We changed the coil but it didnt do much. The wires are getting spark but no combustions within those cylinders. It revs up slow. We both are stomped.

swap injectors around and see if the problem moves to a different cylinder.

But there is gas going. When we took the plugs out the 2 cylinders was flooded.

Physically ground the plug and see if a spark happens just swapping parts means you're throwing a rock at the ground and missing you need facts when you work on a car.

All of them do spark, 2 and 3 had weak sparks so we changed the coil for them, it made a slight difference but no much. If I take out the 1 and 4 plug the car wont start but if I take out the 2 plug it idles the same, same with the 3 cylinder.
