Changed mine a few thousand miles ago. Mine was almost completly out. It was really loud when I just turned the key to on to listen to it, man was it loud. And it would start after a few more cranks then normal and would run normal for like a half hour then the car would either die or start sluggin. Really bad when on the highway doing 60 in rush hour. But got it replaced along with my filter with AC-DELCO cause my dad is a parts guy at a GM dealer here in Knox. Now my car is back up to par going on 180'* something miles. God do I love the 3800. By far the best eninge I have ever seen or drove. This is off topic, but my mom used to have a 03' MACH1, she bought it brand new with like 70 miles on it. And after 19,000 miles the engine blew. It had a black box in it that told her she was doing 47 MPH at like 1,300 RPM. Yeah I liked to drive it cause of 300 HP but what a piece of crap FORD. Anyways I just love the 3800'*.
