measure your fuel pressure
Check for clogged catalytic converters since you had mixture problems before
engine light not on . there r no code. so there should not have po420 cattalytic converter clogged. i think is fuel pump problem. need to check fuel presssure. thx i dont know how to do it need to bring to shop. never change fuel filter . or fuel sock ( fuel strainer) nevery changed. my old 2005 corolla 270000 miles nevery go this b4.
i dont know how to do it
It shouldn't be too hard. I think most modern cars have a schrader valve on the fuel rail . You just hook up a pressure gauge (in the range of 100PSI) to it. I built one for about $20. Or harbor freight sells one for $32. If you're really hard up there are places that loan tools.
I don't think you have GDI, so pressure should be in the neighbourhood of 40-50 PSI. Might as well grab a repair manual too.
Cycle the key on an off a few times to see if it builds up pressure and holds is fairly steady for 15 mins or so. Then I tuck the gauge under a wiper and go for a drive and keep watching it.
thx
