Well so much for my idea of just taking the sensor off & running something through the tube, that didn't happen. I got the new sensor yesterday & am happy I went ahead & got it because the old one was packed with soot. The fitting at the top of the tube was packed solid so I ended up removing the tube & had to pick through the fitting that the tube & sensor attach to. The tube itself was in good shape & washed out with brake kleen & weedwacker line pretty easily & the fitting on the exhaust manifold was nice and clear. When I started the engine with the old sensor removed I could hardly feel any pressure at the tube, after the cleaning my finger got HOT real quick when I had the wife rev the engine a bit...lol Hopefully my fuel mileage will increase.
