thanks, I pulled the plug out of the bad cylinder and it was oily.. i then swapped it with another plug and STILL had the same problem on the same cylinder. so I'm getting spark, ill try swapping the injectors within the hour here... I did a boost leak test last week and found a big one on the turbo outlet piping. Threw a new gasket in and was good to go, but ill look into possible vacuum leaks. ill try to get the compression looked at as well. Thanks for the responses, i am a new member, but im an old guest! this is a great forum.

Ive got a rb26dett engine that shakes on idle, and ive been told by a number of people that im misfiring. I unplugged the coilpacks one at a time and the engine responded by shuddering untill i unplugged the coil on the cylinder closest to the firewall. The engine ran no differently if that coil was disconnected or not. I swapped it with a different coil and it didnt solve it, so the coils are good. I checked the wiring harness and grounds, they seemed ok as well. Whats wrong here? I dont know what else to check. please help! can post pics thanks in advance. 1991 r32 gtr 145,000 kms stock, other than 3'' exhaust and turb timer
