2005 Chevrolet TrailBlazer LS Rwd 4dr SUV (4.2L 6cyl 4A)
i have a 05 trailblazer with 98,000 miles on it. havent owned it that long but has been stalling when im reversing and moving slowly in traffic. it starts back up fine then it is ok. it can go a while before it does it again. but it is concerning none the less. brought it to the shop a couple of times with no solution. if anyone has had this problem please let me know if you have an answer.
I have owned my 05 Chevy Trailblazer since it was new. I have the problem with the voltage. Everything will seem to have less power and the voltage regulator will drop about 10 volts and then come back to normal. Have you looked at the voltage regulator when this happens?
I had a similar problem at about 45,000 miles.
It's probably the the throttle body that needs to be cleaned.
It is also known as the carburator.
I brought to the Chevy dealer and they cleaned it.
It's hasn't stalled since.
