No abnormal sounds, other than the engine stumbling at it reaches 800 RPM.
I put a fuel pressure tester on it and I get 35-40 lbs as it's idling.
Here's a weird thing: I can monitor the sensor output as the engine is
running, but I can only 'scan' the computer once, then I get 'Vehicle is
not responding'. In order to get another scan, I have to re-initialize
the scanner.
I'm using an Auto X-ray EZ Link scanner.
