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

Question hi ive got a 2ltr v6 lwb vit my problem is after about 10 mins of driving i get a hesitation @ about 3000rpm then as long as i keep it above 3k its got all its power but if i go below its does tha same now if i turn engine off for a couple of secs it clears tha problem again for about 5 mins then it returns so far i ahve changes changed plugs coils and fuel filter but no difference
any help greatfullly received
thanx simon
Answer Usually, a hesitation is caused by a fuel mixture issue. What about Oxy sensor, and the other electronics? It would be interesting to see how much and in which direction the injection is attempting to correct the mixture. (long term fuel trim)
