MD tuner needed
 

i need some codes remove off my pcm for the rear 02 sensor willing to pay. I hate these damn downpipe codes ive tryed everything. even replaced the o2 sensor

where about in md? i'm in essex and work at Bob Bell Chevrolet in dundalk


i had a p0420 code for months...i added a sparkplug antifouler from autozone to set the rear o2 out further and haven't had any more trouble

Best of luck bump...

...he's looking for someone w/ HPT that can turn off the MIL function for the rear 02 sensor codes he's throwing.

my mistake

i gettin the p0141 code but im sure there is more to come.
