Ray,
Yeah I have an A/F meter. I have not done much yet, as I don't know where to
start. I don't want to spend the $60-$70 on a new O2 sensor if it will not
fix the problem. Also where is the map sensor located ? Is that the other
sensor on the TB ?
I wanna do something soon to fix the problem since it seems to be getting
worse all the time. I don't wanna have a blown motor on my hands !!
