1987 Ford Thunderbird Running rough

Hello, I have a 1987 T-bird, and just put new timing chain on. But the car shakes from the engine not running corretly. It's not the timing though, it is correct I checked it a few times. I have to pump the gas to make it start, then while it's running it like it "hiccups" constansly and runs very rough, but will stay running. I haven't even attempted to take it around the block, im very positive that it would be very slugish. So please I need some help on how to fix this problem, I have to have my car running.


Thanks,
Troy K.
