Hey everyone, I just received a 1987 FJ60. After I got it I did a full tune up on it. I got new spark plugs and wires, new air/fuel/oil filter, and checked all the fluids. It appeared to run much better than it did. I then tried to take it on the highway and it didn't seem to like that very much. It began to shake and the gas pedal would just depress all the way down without causing the car to accelerate. Anyway, I managed to get it back home and turned her off. Next time I tried to start it up, it would not idle, it would keep running as long as I kept pushing on the gas pedal. If I let off the gas it would shudder to a stop. I have a feeling it could be a problem with the carburetor, but I'm really no car expert. Any help or advice would be greatly appreciated
