Doublju Casual Button Blazer Jacket

I purchased a Delphi FJ10565 CSEFI to MFI fuel injector conversion kit and a set of four Bosch 15703 Oxygen Sensors at Amazon for my 1996 S-10 Blazer. They had these products available and at very affordable prices. After replacing the fuel injectors and noticing a marked improvement, I then proceeded to replace the four oxygen sensors. I did not have any problems with the units near the catalytic converters as they were very accessible and they only required some penetrating oil and the special socket to remove and replace. Make sure you warm up your vehicle for a couple of minutes to facilitate the removal of the old O2 sensors. The units near the exhaust manifold are much more cramped to access, requiring 'crow-foot' removers to replace. The right bank sensor was difficult to remove but the left bank required me to take it to a muffler shop as it had nearly welded itself onto the exhaust tube. Thirty-five dollars later and a new tap/retread job, I had all new four O2 sensors on. The level of smoothness is highly noticeable. I thought that the fuel injector replacement had made a sizable difference, but when I added the replacement of the O2 sensors, the difference was remarkable. Without ignoring that my vehicle has now 178K miles, the level of smoothness and performance is outstanding. I will be checking the MPG as I was getting an average of 13 MPG; regardless, the Blazer is, once again, reliable to drive.
