1994 Mazda B3000 Q&A

1994 Mazda B3000 Question: Why have I lost so much H.P. on low RPMs? almost wants to die when starting off.

I have just replaced Rotor, cap, plug wires, & plugs. Helped a little, but not enough. -
Answer 1
Exhaust restriction maybe? Any rattling noise from under the truck when running?? Possible broken catalist in converter. -
Comment 1
Not so much a ratel as an exhaust leak. It's between the headers and the cat. -
Comment 2
Rubber hammer...tap cat...listen for rattle. -
Comment 3
Maybe plugged cat caused the exhaust leak? -
