Jeep Grand Cherokee
Fault codes car is giving out:
Jeep Idles Rough at stop. The car seems to idle around 600 RPM's but starts shaking and the RPM's drop to almost 0. Sometimes it dies there but most of the time, it ALMOST kills, but then Revs way up to around 1500 RPM's, then goes back to around 600. Problem seems to occur when car is warm but I'm not sure.
Jeep has hard time accelerating. It has a hard time taking gas at 10 MPH off and on all the way up to around 25-30 MPH. Also seems to occur when car is warm but again, I'm not sure.
My Catalytic Converter was stolen off the vehicle. I replaced with a $100 after market converter with an O2 sensor. Car seemed to run fine before it was stolen. Also, a mechanic believes the converter that I bought is too small for a big engine (4.7L) like mine. He believes it restricts the airflow and throws off the O2 sensors. I took it to a Muffler shop and had the airflow tested, they said it was fine so I'm not sure what the problem is.
Thanks in advance!
have the same problem?
