When started the gauges don't light for a few seconds and jump right then back

It sounds like the MIC (mechanical instrument cluster) is doing a self test. Have the battery and starter tested, it could be that even though it starts, if the battery voltage drops below 9volts the MIC will do self test (the gauges will sweep). Many times people will assume that if the car starts the battery and starter must be good, but that is not always the case. A good battery will hold a minimum of 9.5 volts cranking and really should hold even more - like 10-10.5 volts. The starter can also affect this if it draws higher than normal current it will drop the battery voltage below the minimum. Most late model cars have a gear reduction start and will crank fast enough to start even when the battery voltage drops under 9 volts - the point at which the MIC will "reset" and do a self test. It is more likely a battery issue than starter, I would replace have the battery tested first. Robert Grove, ASE Certified World Class Technician www.MalibuMobileMechanic.com
