Can't go over 60 mph

Sigh... My Jeep can't go over 60 mph. Even if I stomp on the gas. This started a month ago then I replaced my spark plugs and o2 sensor due to they were covered in carbon. I very rarely go on the highway but this is worrying to me.

This makes a lot of sense in your situation. Plugging of cats is accelerated by a Jeep that letting a lot of un-burnt fuel into the cats. That can be the case if your O2 sensor was bad for a long time, causing the Jeep to correct for what it thinks is a bad Air/Fuel ratio.

We have some Replacement Catalytic Converters if that turns out to be the issue. I can get you a quote if you'd like!
