1996 Nissan 200SX-SE 1.6 liter, 146000 miles. Car is sputtering, hesitating, and sluggish when shifting gears. When at crusing speed it seems to run fine. Changed plugs, wires, distributor, cap, rotor, cleaned K & N air filter, and ran fuel system cleaner through it. The problem still isn't fixed. What else should be repaired/replaced? I also noticed some smoke coming off exhaust just under the engine and gunk around the oil drain plug and oil pan.
