Four problems related to emission control have been reported for the 1996 Chevrolet Blazer. The most recently reported issues are listed below.
Three of the fuel injectors started leaking at the same time causing the oxygen sensors to burn out, which should have been detected when the vehicle was in for drivability problems on previous occasions with no correction. All the front ball joints had to be replaced before 35000 miles due to failure, which resulted in severe noises and vibration in cab of vehicle.
Both O2 sensors have been replaced (at seperate time in past 4 months). Upper/lower ball joints are in need of replacement. According to dealership (desantis Chevrolet) should have never passed inspection in April. Have had problem with abs since purchase of the vehicle. First recall did nothing to fix problem. Abs can't tell difference from wet & dry pavement. Abs will kick in when slowing down on gravel at 20mph, but not at faster speeds on wet pavement.
Oxygen sensor failed.
Consumer states the exhaust gas recirculation valve was damaged and the oxygen sensor are not working as they should.
