Hey guys, last month i posted up about my 2006 Wrangler Sport I6 with the check engine light on. I checked the codes and got the following...P0031, P0037, P0051, P0057 all indicating Heat Circuit Low? I replaced the O2 sensors and still had the same lights on.
I had noticed that the Jeep was a little sluggish, especially when i ran the a/c. Last month I changed the plugs, air filter, oil, and gear oil as well. i drove the Jeep 160 mile last night when it started loosing power fast. The check engine light blinked a couple of times and I gradually lost speed down to 35 mph on the interstate. I limped to the rest area ahead and called my buddy to tow it back for me.
It idles fine, I just have no power. With the o2 sensor codes would it possibly be plugged cats? I was also leaning toward a fuel flow issue? My fuel gauge has not been working, sending unit/filter?
Any ideas where to start?
