Engine Performance problem
1997 Jeep Wrangler 4 cyl Four Wheel Drive Manual 129000 miles
i keep replacing the O2 sensor up front, when the code tells me. It has a new cat on exhaust and O2 sensor back there is good. Engine code also tells me it maybe a vacuum leak. Well I noticed the CCV elbow is cracked near the valve cover. Could this be the vacuum leak that keeps messing up my o2 sensors? When engine light comes on, it smells of gas in the exhaust, and hesitates some. When I change the O2 sensor. It runs good for about 800 miles. Any help would be great
have the same problem?
