1997 Chevy Blazer 6 cyl Four Wheel Drive Automatic 54k miles
My grandfather recently passed this low milage truck my way and it is in exceptional shape overall. It had a small exhaust leak, which I took to my local shop to have repaired. After driving the now quiet truck for an hour or 2, the check engine light comes on. I return to the shop and they inform me there is an 02 sensor issue, but that I may want to drive it a while and just have the codes reset, which I do.
After a couple of weeks of having the codes reset at my local auto-zone, I finally replaced the sensor (bank 1, #3) Within a few miles of having the code reset, the warning light is back on with the same code.
I replaced the sensor located between the converter and the muffler. Was this the right one?
I'm a fairly competent weekend wrench, but I'm at a loss on this one. Computers and electronics are not my strong suit in auto repair.
I'm also strapped for cash, being a full time student and really don't want to have to go to a GM dealership and bow before their service writers.
Any ideas? (The diagnosis code is P0144)
have the same problem?
