I have a 94 GT it has 170,xxx on the motor. has bbk cold air, bbk long tubes, and smog pump delete kit on it. having some runing issues, when i first start it up when its cold it barely wants to run even if I give it a few to warm up still tries to die on me. even after I get it runnin down the road it feels like it has a bad miss in it. through the shifter you can feel the vibration from the motor. occasionally it will all of the sudden start running real good it will almost jerk when it happens for the sudden increase in power! I just tuned it up fresh plugs wires cap rotor oil change. no difference at all. when I went to clean my air filter there was a bit of oil in the intake tube. when I give it the gas sometimes it does pop and backfire, but i cant tell where its comming from the intake or exhaust. Also I did notice that a few of my plugs where really gray almost white from running lean im guessing. I know my way around a motor pretty well just stumped on this one if anyone could give me a hand on this one i would realy appritiate it. thanks jake
