2001 Volvo V70 XC Q&A
2001 Volvo V70 XC Question: Engine warning light comes on intermittently but car seems to be running normally.
My '01 V-70 XC occasionally but not always has a "Service Engine-Urgent" and orange ! light come on when I start the car. Operation is normal and engine seems smooth so I plan to drive to the dealer tomorrow for a diagnostic. Last night the engine was rough and wouldn't smooth out--couldn't get going over 20 mph so took it right home. Today, no problem and no warning light. Any ideas? - beavis11
Sounds like you have a misfire condition that is intermittent. If the engine light ever blinks, then you have a catalytic converter damaging misfire and you should drive your car as little as possible until the problem is completely repaired. - dandd
