Getting an intermittent Code 172 & 176 (lean O2 sensor left and right), mostly on the highway, occasionally in town.
Engine is all stock, runs fine, old plugs & wires, 90K miles.
If I just got 1 side showing lean, I'd assume it was that oxygen sensor, but with two showing I think it's really lean and not a sensor fault.
Additional possible symptom is that I occasionally get a weird, strong alcohol-like smell at idle, mostly when cold. Been happening for months, I'm busy and hope it'll go away ;-) Not yet...
Where should I start looking - the obvious "clean the injectors", or somewhere else first ?
Thanks!
