The dealer tells me I need new catalytic converters. \>$3500.00 US  
  
 Perhaps they were poisoned by a “Cheapie Lube” attempt at fuel injection cleaning.  
  
  
  
 Is it possible to disconnect one plug wire thus causing he cats to get very hot and clean themselves?

First get a second opinion from a shop that’ll actually put the oxygen sensor traces on a scope. Veryify that you actually need new converters.

No, it is not possible to disconnect one plug wire and cause the cats to get very hot and clean themselves.

Dealers sell lots of expensive cats unnecessarily. Often new O2 sensors will fix the problem.

Get another opinion.

No, you can’t make the cats get very hot and clean themselves. They already get very hot.

Darn I thought this was a question about killing cats or BBQ’ing them. Disconnecting a plug will only foul it more.
