Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hello, I'm Brandon.
A plugged up converter can make the vehicle stalled.
Technically you can run the vehicle without the converter. However it is illegal to do that due to emission.
Also your vehicle will run rich and fuel consumption will go up.
The proper way is to replace it with a new converter unit.
Please rate me positive, Thank you!
