My 97 TJ sometimes chugs when stopped at a light. It will idle fine and then a little chug will occur... about three times in a row. Any ideas what it might be? It runs great otherwise. Timing belt?
That could be any number of problems. Run your codes and see it may be a very simple thing like a sensor or fule filter or about anything. When did it last get a tune up. Good Luck in the hunt for the chug monster. Tug[addsig]
