A few weeks ago I had an exhaust hanger break off the pipe, the hanger near the exhaust flex hose. Patched the hole and drove it like that for a few weeks, the exhaust was hanging a bit low due to no hanger. Started to have trouble with the car stalling when coming to a stop, giving it a bit of gas would keep it from stalling. Some days it ran fine, other days I had to slip it into neutral when I came to a stop and give it some gas to keep from stalling. Check engine light came on. I thought the wires for one of the O2 sensors may be getting pulled on causing the problem. Had the front exhaust pipe replaced, and the car ran fine for 3 or 4 days. Now it is doing the same thing again. I tried to play around with the O2 sensor wires to see if it would run smooth but couldn't get it to run properly. Any ideas what to check next?Thanks in advance. Glen
Checked the codes, 2 misfire codes and 2 EGR codes. Can the EGR be cleaned on a 97 corolla? 1.6 ltr???
