It'* been on for a while it will come on and off. Sometimes if I step on the accelerator the Trac control active message will come on and cut power to the wheels for a few second let off the accelerator and the abs/Trac and traction control message will go off. I don't no maybe a faulty sensor or wire in the hub bearing I don't no I change the passenger side in the beginning of the year. And also under hard acceleration my truck cuts power of dosent stall just no power until I step on the brakes and then a few second later the power comes back . Ive been reading a lot and it could be anything from the fuel pump to the fuel pressure regulator maybe sparkplugs and wires I don't no where to begin and there'* no check lights. Any thoughts
If met with your situation, I would also suspect the abs/traction system is to blame, and I would address that issue first before trying to address any further drive-ability concerns. I also suspect it'* likely one of the wheel speed sensors, however the readings are not erratic enough for the system to recognize a fault. The only way to diagnose it presently that I am aware of is to have a tech ride shotgun with a scanner plugged in to determine the reason for the system activation.
Unless you wait long enough for the problem to worsen enough to set a code, which will need more than a basic code-reader to pull.
It could. One of the ways the system reduces wheelspin is by pulling power. I wouldn't know if your case is caused by it without looking at the truck but with known issues you may as well address those first and then see where you stand
Funny thing today I was checking the motor and something told me to check the battery cables come to find out both beg and positive where lose so I tighten them up turn the truck on an no abs/Trac light have to wait and see if it will come back on
When I step hard on the accelerator sometimes the truck cuts power and I have to slow it done and then power picks up. It dosent stall though which I find weird. What can cause this issue.
Can a fuel pressure regulator cause this and should I replace it or maybe the spark plugs. There is no check light.
And also for over a year I have this hesitation when the trans changes gear and there'* a slight Rev when gear changes if it was the trans it been toasted by now for sure and also when it'* 90 and above before my trans temp would read 150 degrees now after a lil while it reaches 200 degrees. Should I drain the trans fluid and change the trans pan or just leave it because the fluid looks light dirty brown. Any thoughts
I'm puzzled when I drive my truck and under hard acceleration my truck would cut power but not stall basically when it cuts power I have to come to a complete stop then it will have power. There'* no check light the only light I have on is my abs/ traction light which comes on and off at random times but mostly stays on. Could that be what'* causing my truck to act the way it is or could it be fuel related. I have changed my plugs or wires since I had the truck should I try and see if that fixes it.
As I said in your previous thread that you created for this very issue, GM has been known to pull power by various means when wheelspin is detected. With your intermittant ABS/Trac lights, I feel it would be best to either diagnose, or disable it and see where you stand.
