Hi Shoprat and Maineah,
Thanks for answering my post. The sensor is working. But as far as I know, it is the orignal sensor (past 80,000 miles). The manual said it is the be replaced at 80,000. No biggy for me to install the sensor.
A few of questions:
1) If I replaced the sensor with a new one, should I see an improvement on fuel milages?
And, my Dolphin id a 21 footer. The exhaust runs clear to the back of the Dolphin's rear bumper (one long tailpipe, whew!) Anyway, if I shorten the exhaust pipe to exit behind the rear tires and between the leaf spring (I've seen a few of them on the road with that setup), should that help the engine as well?
2) Sooooo, between the sensor and tailpipe shorting, would that help increase the fuel mileage?
3) Also, has anyone been/tired using the Flowmaster mufflers?
Thanks,
(please answer each question independantly)
