2004 Grand Prix GT 3.8 L stalls
In the last month my 2004 Pontiac Grand Prix GT stalled twice while driving. The first time, it won't start before I shook some spark wires randomly. The 2nd time it started after I've stopped the car on the right side of the road.
A scan with ScanXL software with the GM module, didn't find any trouble codes. The only parameters that appear in the freeze frame data, which, I guess, may be related to the problem are GM.ENGINE.IGN_V (Ignition Voltage), GM.ENGINE.MF_CYL#C (Missfire Current Cylinder #) and GM.ENGINE.MF_CYL#H (Missfire History Cylinder #). There are many others parameters in the freeze data table.
I've also recorded a few minutes of real time data for the parameters mentioned above. Unfortunately, I don't know to interpret them, so I don't know if the freeze frame or real time data show any problems.
My totally uneducated suspicion is the crank or camshaft sensor, but...
Any help is appreciated!
