I would like to know if any one experience with their Jeep when in neutral it revs OK, but when in drive and in motion seem to run ok upto 45 mph then gas pedal to the metal slowly increasing speed upto 55mph it feels have no power I can go only about 2000 rpm, and no power going up hill.
I took the catalitic converter and look inside all the stuff inside come apart all is left is two pieces. It seem I don't see any clogging I can see thru and looks like a straight thru pipe. Where could be the clogging is at the muffler? I'm still confuse, do you need back pressure and the catalitic converter providing he pressure? I'll try to test drive it without muffler and cac attach to it and see if I gain the power back.
