Default Falling on its face

Hi there, I have yet another problem with my 87. It was running great, I parked it in the garage. The next day, I got in started it and it had a dead spot it the throttle. It starts at about 1500 RPM's and continues till about half throttle. It then picks back up, but is lacking a little. I thought it was the TPS, but it meters good. The MAF readings look good. This problem does get a little better when it gets up to temp. What do you guys think, clogged CAT? Fuel filter? Fuel pump? I thank you for any input you have, this forum has been a life saver with this car.

I think I got it, it the shop that installed the motor, installed the wrong spark plugs and they failed. You just can't get a good mechanic anymore.
