I picked up an '83 pickup not too long ago that I was told had a bad cat-convertor and wouldn't run for more than a mile or two. I towed it home, put on a new cat, muffler, oxygen pump and a tune-up. The thing runs great now except for a surging when it gets up to speed. It almost seems like it is starving for gas when you reach any cruising speed (35, 55, 60, etc). It has plenty of power all the way through the powerband, as long as you are giving it gas, but as soon as you let up it surges terribly. I've replaced fuel pump and filter, but am not sure what to do next, any ideas? The carb is the electronic 4-bbl, which from what I understand is nothing a backyarder wants to take apart? New carb will run about $400 and rebuild is around $350 at a reputable shop. The area that I live in prohibits the removal of all the emission stuff, so am I stuck with getting a new carb? Thanks for any help you guys can provide!!!
