oxygen sensors

I'm saying an "area with no rust" ....would not be me. I live in the Baltimore, there's rain, snow, sleet and rust just waiting to form...

I was agreeing with the previous poster.

All your problem could be due to plugged cat. converter or atleast most of the V8s

I thought the same thing about my 90 525i....but the mechanic swears it's the air mass meter. The car just acts "congested". Let's not even talk about sitting in traffic, it worsens...but not only is it more throaty...it just seems clogged. I'm thinking about just having the cat replaced. Between the air flow meter sensor thingy and the catalytic....I figure I'll spend about the same amount.
