another cat problem
A couple weeks ago my CEL came on (misfire cylinder #8) my first thought was plenum, so you don't have to reply with a link to the thread. I checked my spark plugs and they were all bad didn't look like they were ever changed. So I changed them and it ran fine, didn't get the CEL again.
This past weekend I was driving and I could hear the engine misfiring on a hill and the CEL came on again, I let off the gas and made it up the hill, got to the top and just cruised down, the light went off, and didn't come back on. No code came up when I checked later.
So I'm planning on selling the truck soon so I don't want to start digging into the plenum, but I think I have to replace my cat. Just want to make sure before I order one. I have to do this quick because I need to go somewhere on Sat. about a 3 hour round trip. And I need to take my truck.
