Re: clogged cat converter?
Behind the manifold on the drivers side is the schrader valve to check the fuel pressure- CHECK IT First- Running and not running. The multiple misfires is associated with fuel NOT Cat Conv. PSI should be running 54-60 psi shut truck off and watch the gauge does it stay at 58 psi or does it drop-?
If drops chnage the the cpi unit under the manifold and the fuel lines feed/supply- let us know the results..
