OK, here is my somewhat embarassing question. Today I ran some seafoam through my engine, then drive it around for a while, and it ran fine. I came home and replaced the spark plugs. Now, this is the first time I've ever done this. Now when I drive it, it will start up fine, but if I get under any kind of acceleration, it will start bucking, like as if I was pressing the gas hard then letting go quickly. I checked the spark plug gap on all the plugs before I put them in, they all seemed right at .028 without adjustment (NGK BPR7ES). What else should I check? Could I have put the wires back on out of order or not tightly enough? Could I not have tightened the spark plugs enough? Etc?
