Deve If you have a spare wide band sensor in the workshop i would be very interested to hear what test results are coming out of your multimeter testing ! Thanks for your tech updates. After i have been reading your websites i have some questions about the tech. updates you have done with your Deluxe truck . Questions about the front disc brakes , and about smaller parts i will be needing for my truck when spring comes in 2017 . Hope it is ok that I send you an e.mail in the matter ? Martinius.
