| Injectors went bad and pulled the plenum to replace with 300degree fuel rail and new style injectors. Deleted and rerouted under plenum hoses. Deleted/Plugged EGR. Also installed Selin Kit with Dual intake. After putting everything back together the car runs extremely rough like it is missing cylinders. It is smoking (white) out the back with a heavy smell of fuel. Also the car cannot rev past 3k. Ran codes and originally got a 21 code (PTU). Tested the PTU unit itself for continuity and it passed. Also tested the fat middle black ground wire on each coil pack connector with plenum ground ( passed). Tested the small black wire with on the coil pack connectors (passed). Tested the signal wire (colored) from the ptu to the coil pack connector and see a complete connection. Redid the two grounding connections on the back of the plenum and they are solid. I replaced the PTU, anyway, but still the same problem. Code 21 has gone away and now have 55. When I pull the coil pack connectors when the car is running it seems all of the cylinders on the passenger side are NOT operating. There is no change in engine rpm when I pull those connectors. HELP! What should I start looking at?
