Customer Question
Check engine light is...

Check engine light is perpetually on for years due to o2 sensors needing replacing. I don't want to\he expense of changing them out. Today it flashed for the first time when it was cold. Codes read cylinder 3 misfire, but it stops flashing when warm. It needs a tune up, but the question is should I drive it at all.

Mechanic's Assistant: Does the light stay on, or does it blink?

I let it stay it stay on for the o2 sensors because I don't want to replace them, but it flashed on and off for 5 minutes today when cold.

Mechanic's Assistant: What is the model/year of your Jeep?

2006 wrangler

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

No, never

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

No, thanks

Hello I will help,

It will get progressively worse unless you fix the problems til the engine will not run at all. It just gets more expensive the longer you wait. The flashing means a catalyst damaging misfire so your catalytic converters are being damaged.

Please let me know what I can do to help you with your questions

Thanks
