Inspected the ETM connector, no issues found.
ETM installed, cleared codes P0300, P0137 three times in half hour, they come back.

Thank you

Dismounted, opened, inspected, reassembled, and cleaned the ETM.

Here are the housing numbers.
ETM

Interesting, I will closely inspect the connector for issues.
After I reinstall the ETM I will recheck codes.

The continuing saga.

Random throttle fail while driving = any speed it suddenly drops to idle, 7 to 100 seconds it begins functioning again.

My first assumption is a failing TPS (Throttle Position Sensor ...

Good afternoon.

The saga continues.
New PEM connected, the fuel pump runs, it started and idled strange.

FYI: Found the issue is a broken crank position bracket.
For anyone not aware, this is a plastic bracket with a threaded stud.
Apparently when I replaced the sensor, nut removal started ...

Might be worthwhile starting a new thread on your headlight issue. Sometimes when you have a major issue things like this can get missed.

When you say headlight, do you mean the whole headlight unit is not working or just the actual headlight? If it is just the headlight, have you tested the bulb ...

Your help is appreciated.

The PEM module has been removed.
Following advice of many sources, shaking the old module sounds like a Maraca.

How do you know your 2003 does not have the PEM?

Blind groping I found the PEM right front top of the fuel tank.
It will be replaced when the new part arrives.

Thank you so much.
