Troubleshooting
most likely a bad body ground or a alternator going bad. easy to check out put of alternator with a simple volt meter. if 13 volts or a bit higher you are charging. is the truck idle staying even or is it dropping? a very low idle below say 400 may cause the condition too.
My 2000 z71 tahoe shakes for no reason
you may have a vacuum leak or a spark misfire.Take it to a reputable shop to do a diagnostic on it, could be as easy as a bad wire or a vacuum line disconnected...If all that fails the throw a blanket at it, it may be could....Good luck!
Should i drive in auto all the time
you should drive in 2 auto, unless you are in conditions where you may need 4 wd then you can put the tranny in 4 auto. You don\'t want to drive all the time in 4 auto because you keep power to a solinoid all the time and will cause it to go out sooner.
Security light is on and my 00 Hoe will not fire. Will turn over.
The security, antitheft, or passlock light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link may help you find ways to bypass this or fix it yourself.
