2 Crankshaft Position Sensor problem of the 2007 Chevrolet Trailblazer

Failure Date: 06/05/2014

Vehicle stalls and shuts down everyday. Sometimes just stalls then accelerates, sometimes shuts off and I can switch to neutral and restart while coasting. Other times I get shutdown warning light and engine will not restart. I have to coast to the shoulder and wait. Engine will then struggle to restart and engine shakes violently. I wait a few minutes and it will start and run fine, sometime with check engine light on, sometimes not. Rpm gauge works sometimes, sometimes not. At time there has been no response when turning key to start. On going issue!! crankshaft position sensor has been replaced 3 times, and issue still persist. Major safety issue!!.

3 Crankshaft Position Sensor problem of the 2004 Chevrolet Trailblazer

Failure Date: 01/04/2012

Car felt "stuck" in gear, wouldn't accelerate, low on transmission fluid. Added more fluid, replaced speed sensor, camshaft & crankshaft sensors. Still having issues with rpms going high, car slamming from one gear into another. Also cannot run heat while driving, fan draws power & causes engine to stall out. Car also burning through gas very quickly.
