Hi all.
Trying to figure out how to even start troubling shooting this. Owner before was meticulous about noting maintenance stuff and babied the car; sunday drive to church parked in a garage. Then when it got to me, it got the college kid treatment, parked out in in a lot during the worst Northern MN winters and that polar vortex last year.
Anyway, trying to figure out this out, I don't get the code during the summer months or if i have the car running and clear the code, shut it off and then restart it. IE it's warmed up. This leads me to suspect there's something going on related to expansion (I also think I read something somewhere re: intake manifold gasket leaking when cold)
The $06 pass except for the "Exhaust gas sensor bank 1- sensor 1" reads 8.0/9.0, minimum is suppose to be 10.0.
Any ideas on where to start troubleshooting? really don't want to through more parts at this than needed.
