today my car was extremely tempermental on me, stalling sometimes but mainly when I shut off engine it would not wanna start and would frequently backfire at the same time engine died when trying to start engine. After quite a while of trying to get it started, it would miraculously start up normally and I could go again for a while until I shut off engine whereupon it would do same thing all over again.
I have taken a tester to the plug under the dash and got codes 13 and 44 which are oxygen sensor related codes from what I understand.
I havent been able to replace O2 sensor yet and am wondering if I might also try looking elsewhere for other problems linked to the backfiring or if said backfiring is caused by O2 sensor problems. Any information would be helpful on this.
By the way, it currently has approximately 217,930 miles on it, uses no oil between changes and also has no coolant issues. I am somewhat impressed with this car even though I am not a true chevy fan.
