Here's the conclusions to the Chevrolet vehicle we test drove last time.
After the drive cycle, the following issues were taken care of:

*frequent stallings while driving, and even when the engine was idling.
*exhaust black emissions

But what was left outstanding was that despite the test drives, there was still loss of power. It was like the vehicle was being stalled of fuel, or bucking down.
So, what we did was to replace the already purchased crankshaft 24X sensor behind the crankshaft that the car was using, to the one that was originally there. Test drove the car again, the issue was resolved.
Those were just the updates we wanted to pass across to you guys.

The video of the entire work process can be found here:
