A clogged converter can cause rough idle, engine hesitation upon acceleration, weakened power, hard-starting and, in some cases, a no-start condition. … This symptom can be diagnosed by using a vacuum gauge on the intake manifold, or an exhaust back-pressure pressure gauge before and after the converter.
Drilling holes on a catalytic converter is never a good idea. By doing so – you allow toxic gases to leak out. At best, this will pollute the environment. … The toxic gases are odorless and colorless – so you wouldn’t even notice them.
