So I don't have a CEL but I've got a stored P1294 and a pending P0303 code. I reset it again, hopefully they don't return.

I did notice that the OBDII connection quit once I started the engine and I couldn't reconnect until the engine was off and ignition was on. Could my ECM be failing?

What tool are you using to read OBD II codes?

So the Jeep passed emissions! :D

However, I was only able to get about 150+ miles before I got a cylinder 3 misfire...... :lol: :roll:

I'm not sure why it's so inconsistent, any ideas?
