I have a 87 supra NA auto. Couple weeks ago its started acting crazy. It run fine then all of a sudden at a stop light it would run on 5 cylinders. I did a full tune up (spark plugs, spark plug wires, distributar cap, rotor). The damn car is stilll not running right. It seems its still running on 5 cylinders. I am planning to change the fuel filter cuz im thinking its old. Anything else you guys would think would be going wrong. Thanks in advance
