I have a '96 Toyota T-100 pickup, and the engine light stays on. I went to Auto Zone, and they check it with a tester for free. They said my 0-2 sensors are bad. I also heard that when they are replaced, they have a tendency to strip or break, and this means a bigger repair bill.
Are they hard to replace? Can I do this myself?
2nd question....When I open my gas cap, I get no pressure release. My mechanic says it alll depends on what system was used on my vehicle. How can I find out if I have a pressurised system, or not?
Thanks....
