I just recently swapped an engine transmission combo on my FC and after the swap I was having some problems running the car. It would Idle fine, but around 2500 RPM it would make a chirping noise. when in gear this would cause the car to buck back and forth. I actually am engaged to the daughter of a mazda master tech, and asked him to take a look at it. After a half hour run through of the car, checking everthing from fuel injectors to plug order we finally found that I had hooked the plug wires up in the wrong order. If anyone is having a similar problem, please check that everything having to do with your firing order is as it should be.

My FC runs great now, back on the road after I bleed the breaks and fill the transmission with oil.

What order were you using when the problem occurred?

I had the leading and trailing mixed up, so at low RPM's it wasn't really noticable, but as the engine spun faster the plugs were trying to push the engine backwards.
