Whats up everyone. Well I took off my test pipe and put on my new carsound since im gettin ready to do emissions and i got 2 Cels when i installled it and a rough idle. The scanner said p1298( Manufaturer control fuel air metering) and p0141(o2 sensor heater circuit malfunction Bank 1 sensor 2). I unplugged both of them a couple times and clipped them back in and they still popped on right away. Can anyone tell me what these codes are for? I replaced my front o2 sensor not to long ago but the back is old so could it be that my back o2 sensor just took a **** and i need a new one?? Thanks...

 

anyone have any ideas??

 

did u plug the o2 senor back in? double check that

 

P0128 Cooling System Malfunction

 

Second code was p1298 not p0128. Yea i unplugged them a couple times and plugged them back in and as soon as i erased the light with the scanner and started the car the light would return with a rough idle and these two codes. Did this like 5 times to make sure...

 

Well i wnet outside this morning and check my fuse panel under the dash and sure enough my alternator fuse was blown. I replaced that and it runs fine now..
