It's only firing on 2 cylinders. Replaced almost everything. Plugs, wires, battery, alternator, ECM.

Hi,
Did this happen all at once? Have you scanned for diagnostic trouble codes? Here is a quick video showing how that is done:

If you have replaced everything, then we could have a fuel injector problem or engine compression issue. Here are two links that explain how to check both:

Also, let me know if you have checked fuel pressure and for a plugged catalytic converter.
Take care,
Joe
