How to diagnose and resolve engine issues using Durametric.

[jb92563]

Update -

I tried swaping out the Throttle Body and the E-gas pedal potentiometer/sensor and still no luck.

The car starts and idles ok but does not respond at all to the gas pedal.

It just seems like there must be a fuse somewhere thats blown but all the fuses look good except the drivers seat adjustment, which has an issue that I know about.

I also found some more relays and fuses in the trunk but the fuse there looks fine as well.

I also disconnected the ECU in the trunk and used contact cleaner on the pins.

I took the ECU apart and nothing looks burned or fried. Solder joints look good.
I was surprised the ECU is not even a sealed unit, and looks cheap. Any moisture in the trunk would be a bad thing for sure.

As a last resort I have a matched used ECU/DME/Ignition assembly for a 2001 S same as mine, so I'll give that swap a try and keep my fingers crossed.

If no luck then I need to find a very talented Indy with the right skills and tools to figure this out.

Still the same codes for the egas potentiometer, Throttle Body and MAF but those are symptoms, not the root cause, as my swaps have proven.

No Check engine light suprisingly.
