I am having some annoying issues with my Montero Sport. There seems to be some kind of electrical issue or power distribution issue. Which is causing the vehicle's dash and headlights to have a surge in conjunction with the motor. Lights will dim and brighten as the engine sputters a bit. Also the vehicle seems to run fine once I'm at 65mph or more. Sputtering issues occur mostly between 10-45 mph. Electrical surging seems to be most common when sitting idle.I've had to change alternator twice in 2 years as well.I'm kinda at a loss now. Being a single dad is tough and now this. Any help to be offered would be so appreciated.
