My mechanic can't figure it out he's been in the business for 20 years ... The whole ignition system was replaced timing belt and water pump valves adjusted fuel filter was done he checked the injectors everything ... Except he didnt check the 02 sensors . He must hve not thought about that . And I replaced the cat today .. So if I check the 02 sensor what am I looking for? Can I clean it? Cuz I can't afford another at this time I'm broke . I just got hired at Taco Bell it's ironic cuz I can't even make it to work so I can buy new 02 sensors smh... Btw the car doenst smoke at all but does have a lot carbon build up on the tip of muffler and the muffler goes ba ba ba ba ba ba
