(forehead smack) Matt's dead right, I totally forgot about manifold vacuum leaks, not only that, my car had the same problem and I overlooked the cause! Mine, idle was bumpy, cyls 1 and 6 weren't contributing, yet power was fine plugs clean and same as the others... stupid iron intakes warp, and no amount of bolt-tightening will flatten it. Matt's tune up method is best too. But it should idle decently, if not correctly, at 2 turns out on the mixture screw. That's a "barn door" target, and a basis for tuning. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
