Will it damage anything if I drive the car with a p0181 fuel temperature sensor alarm? It doesn't drive well.

Bring it in so we can take a look at your issue.

U should take it in before it affects something else

You could be damaging your catalytic converter if you are driving the vehicle with the check engine light flashing I would highly recommend having this vehicle towed to the dealer for repairs

I really don't know about that u would have to call and ask
