OK, I posted this on the MAF thread but maybe it wasn't the right place, because I didn't get much response...I've got a 2000 GLE, original owner, with 78K miles on it. For a while now it's been pinging just after starting. It probably does have a bit less power than when I bought it. I had some bad coils (P1320) but replaced two of them and haven't had any of those codes since, so I think I got them all.

But now I get intermittent P133 and P153 codes, at the same time. BOTH O2 sensors slow response? As my local mechanic pointed out, it seems unlikely that both O2 sensors would fail at the same time. I get the codes always on the highway, maybe after a while doing 70MPH on the freeway, perhaps once in a 150 mile trip. I can clear the codes with my code reader or they will go away in a few days of city driving. Last week I took several road trips and got this pair codes, always together, three separate times.

Any idea what could be causing this? My local mechanic hooked up his computer to the car and said the knock sensor and the O2 sensors were all checking out OK. His idea was to change the sparkplugs but reading through the forum, no one seems to report much improvement with changing the plugs early (aren't they good for 106K Miles?) MAF? I've never had a MAF code.
