AboutDavid Scott Expertise Questions regarding the advisability of different kinds of modifications to Samurai/Sidekick/Tracker or various kinds of off-road usage. I will not attempt to do more than provide links for questions about other Suzukis such as Vitara, Grand Vitara, etc. I may or may not give generalized advice for newer models, but have no experience regarding newer models, and will not attempt to give more than the most generalized answers for questions regarding vehicles later than '93 manufacture. I will however, if possible, provide a link that will help you contact a professional in your region.
Experience I've been a professional mechanic for over thirty five years, live in the center of the Rocky Mountains, and have been active in exploring the old mining/4wd roads for decades. I've specific experience with Samurai modification, because that's my personal vehicle.
Education/Credentials Thirty five years of advanced, intensive classes for experienced professionals only. Manufacturer seminars and training classes averaging four to six weeks per year. I'm now a professional heavy duty fleet mechanic, and no longer deal with issues such as MIL (check engine) lights
Expert: David Scott Date: 6/2/2008 Subject: Emissions failed
Question Why would my 1993 Suzuki sidekick fail emissions? He said it was the Nox part.
Answer I haven't done emissions since 89, and am now doing fleet diesels, so my knowledge of this is out of date and limited. In addition, Colorado, my state of residence, being a high altitude state, does not have nox issues.
the following could be at fault:
Timing too advanced, EGR valve inoperative or nearly so, Catalytic converter, oxygen sensor.
