My brothers low trac and brake lights flash at a red light more rpms anfd the lights go out? I need help is it a vacuum Leak?

 

Sorry they barly light up but they flash all the time the ABS idol light stays on also. Any help???

 

Umm can you please reword that correctly with proper grammar, so we can understand what the situation is.

Sounds like your car battery is dying out.

 

OK here we go. My brothers 94 Z-28 Camaro has a problem the low trac and brake light bearly flash and the ABS light stays on. Does anybody have any help??

 

If you are low trac is on, that means there is a problem with speed sensor on your wheels. The computer isnt reading the sensor properly. Or it could be the wheel speed harness is damaged

 

Didn't know they had those.

 

I just started having this exact issue today after I cleaned out my TB with TB cleaner, then it randomly stopped, but when I turn my car off and back on they flash for a few seconds then turn off. Went to AutoZone had it scanned, nothing abnormal. I took a look at the schematic turns out Low Trac, ABS, and Brake lights are clustered together...

I think getting the IAC sensor wet with the TB cleaner must have done something, when it started to dry off it started running better, and lights went off.

Edit: Also, correct me if I'm wrong, but after the car is running the battery shouldn't be an issue since the alternator is going.

 

I fixed my lights and here's how. Check the ground near the power steering fluid bottle. There a nut on that then some wires, and then another larger nut with a big wire underneath, that was loose on mine, tightened it and everything is good now. Hope this helps.

 

That same nut was loss tightened it up now heres another problem the battery seems to drain down if not run in a couple of days. I put the battery charger on so we'll see if that fixed the idiot lights.
