ehhh i got bad o2 too i think, i took an OBDII to it a cple weeks ago and came up with bank 1 system too rich so i deleted it, CEL light came on bout week or so later i just took an OBDII to it a cple days ago and got 3 codes,p0172- bank 1 system too rich,p0420- Catalyst Effiency Below Threshold, p0171- bank 1 system too lean... wtf! one says rich one says lean?
also when i floor it or close to acceleration is sh*t it'll stick at certain speeds and sound as if i had a rev limiter but after i keep holding foot to floor on gas it eventually slowly increases in speed but if i release gas half way it runs ok kinda until i hit about 55ish then i have let off a lil more. is alll of that just cuz the o2 sensor? do i need a new cat too?
