So i have my




and it has a p0133 and p0140 code, and also a p1612 but the key works just fine so i dunno what thats about.

144,000 miles, no response from the engine above either 3500 rpm or usually 1/3rd throttle. idles at about 600 rpm.

what i think i should do is just replace the o2 sensors and the maf sensor. i'll clean the maf sensor first today and drive around a bit since i have a can of cleaner but other than that i'll just be replacing things.

i'm a greedy/****ty person so i made a thread about my woes before searching for 15 years of literally the same story but i love when its personal. i'll search during the interim but if theres some more specific actual anecdotal knowledge regarding possible causes then i'd love that.

thanks so much, i'm just trying to go about this as a more informed and less haphazard fool.
