MAZDA B2300 CATALYTIC CONVERTER PROBLEM

1995 Mazda b2300 • 212,333 miles

Has no power even when you push gas peddle to the floor. Replaced throtle position sensor, no change. Exhaust Manifold glowing red. Could it be the catalytic converter? How do I check that?

There is a bad misfiring and excessive fuel is getting to the catalytic converter causing it to glow red hot.

Have you checked the basics, spark plugs, wires etc?

I just now read your answer, but you were right. The wiring diagram for the spark plug wires was totally different then the way the truck was wired. No diagram I could find anywhere matched to the way I ended up wiring them. Thanks for the answer.
