Customer Question
I have a 2005...

I have a 2005 jeep wrangler, I removed the rear catalytic converter, when I start the jeep the engine races. Would removing the converter cause this?

Mechanic's Assistant: Has the vehicle been "scoped out"?

No, but it ran fine before the removal.

Mechanic's Assistant: Are you fixing your Wrangler yourself? What have you tried so far?

I have put the converter back on and it still races.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Yes, in the process of cutting the exhaust pipe I nicked a hose or small insulated wire going to the back end, no wires were cut.

No, removing the converter or any part of the exhaust will not cause the engine to race.
