Hey guys, just put in my 19lb injectors in. I am running the miller MAF with the chip. However, soon after putting them in my idle was really bad. i thought that was normal since it was adjusting but after driving it for 30mins it would sputter every once in a while and if i floored it at around 4k it would misfire or just sputter really bad. I got the 1221 engine code for the o2 sensor, took it out and it was black. So my question is would my problem be solved by just replacing the o2 sensor or could it be something else. Also prior to do this my car had no idle or running problems. I also changed my fuel filter at the same time but dont know if that matters. Anything info helps!
Thanks
Thanks
