Mabe one was older than the other, mabe get two new ones and see how you go. i can get you a good price on them if you like. mabe try your old one and see the readings you get.
Yes, you can't go wrong with just biting the bullet and getting 2x new ones if you're able to. In the meantime, if it is running like crap because of one bad one, just disconnect the connector for the bad one till you replace them. it should run better in the meantime.
