Firing sequence on car?

It doesn't change the firing order/sequence, but the distributer does advance/retard the ignition timing, depending on the engine rpm and load

edit: No but that isn't legal

Yes, turning the distributor will advance or retard the ignition. Turn it too far (either way) and your car will run really bad. In the distributor era, that's why people had timing lights.

BUT, it does not change the firing sequence. This order is set, and will not change.

If you remove the cat, you will not damage the car, but you will pollute more. Depending on the vehicle, you might set the emissions codes. On many cars, this does not create much of a performance difference, unless the cat is clogged. BTW, it's technically illegal to do this in the US.

Advancing or retarding your timing has nothing to do with the firing sequence. As to removing your catalytic converter, modern cars with computers are made to run at their optimum with the catalytic converter. It's not like when they first came out years ago with all the emissions. Back then you could remove them. Remove it and you will have engine codes popping up.
