I did recently put new plugs in it. I’m assuming it would be one of the front o2 sensors?

Sounds like it could be related. How many miles on them? Stock manifolds? Or long tubes?

With 1000 miles and you just did plugs id pull the plugs and check them if the car was running great. Could of been a fluke. But never hurts to check.
