installed 8.1L maf sensor on 2001 t/a
now it seems to run a lot richer am i in need of a new computer tune and if so what would be a good tuner to use
i would like to get program for my laptop and teach myself how to tune
there are only a handfull of tuners in my area any suggestion
both front o2 sensors not switching correctly
most likely got wipped out by running to rich
and the LTFT is -1.6 both sides
hopefully 2 new o2 sensors and stock maf sensor
will fix this also had a knock sensor code
any info would help
