Hello i recently went on a test drive with my motorhome while a snap on verus scan tool was attached. I was wondering if the O2 sensor is supposed to do this jumpy bit. Fast forward to 8:20 as the earlier parts are a wee bit shaky.
Is the knock sensor supposed to read around 14 - 18?
This is a 1992 Motorhome with a 454 engine. TBI and 4L80E transmission.
Thanks for any input.
