97 altima has power, however if you step on gas pedal or break, or turn lights on, the car loses all power. there is also a noise behind where the stereo is. battery has enough charge and the altinator seems to be fine.

Hi,

it sounds like there might be an issue with your breaks or breakpads sticking whenever you decelerate from high speeds. Try "pump breaking" or applying the breaks for short bursts of time in order to slow down to see if this dodges the issue. If so, I would still get the break pad or system checked while still mentioning the full issue to the technician. Thank you.

Try to check short on brake pedal stop light sensor and see if something catches accelerator pedal..

check your brake light switch on the brake pedal, more than likely thats where the problem is, when pedal is push down, the plunger on the switch is released to turn lights on, when you let up off the pedal the plunger gets push in by the pedal to wich its mounted, which inturn shuts the lights off. do you see how its suppost to work ? thats the only switch for your brakes , soooo yours is backwards correct ? must need re-mounted in its proper location........... OK

may be its not your sparkplugs, but may be your coil pack usually gives fire to your wires which feeds spark plugs that could be why your losing power, good luck

that is part of the throtle linkage,the plastic ends wear out, replace that arm, you may have to get from the dealer.

Your problem should be that the rubber stops that are mounted at the top of your break pedal came out or are worn down too much to press the buttons all the way in.
What they do is push the button that switches off your break lights when the break pedal is released (yes, kind of backwards way to design it, i know). That's why your lights stay on even when your car is off. I had to go to the junkyard to find replacements for mine and they are a ***** to replace.
They are chipped away easily by the break switches when your car shakes badly over a prolonged period of time. Like driving a couple of weeks on a bad front tire.

check the level of the power steering fluid,check belt tension & condition

Lets keep it simple if the wiring harness is in good condition lets not look at that... first check your fuse if the fuse is good... check for power... if you have power coming and going from the fuse then check your brake switch ( located under the dash) attached to brake pedal. Please make sure your light bulbs are both good also. If your brake light switch is good and you have tried everything else it is either going to be in your 4 way switch or wiring harness

Sounds like a vacume leak from power break booster, when you loose vacume it will stall out the engine if enought vacume is lost. chk. power break booster. and hose from engine leading to booster for vacume leak, booster is under hood, break master cyl. bolts to it.

I had the same issue. It turned out that the break pedal switch was broken. The engine start push button is connected to a second break pedal switch that senses when you push it. That switch is independent from your main break pedal switch that turns on the brake lights of the car.
