Hi Tom,

Glad it's behaving.
Maybe the ECU needed a reset by disconnecting the battery?
This is an undocumented feature of LH2.4 in my 1993 945T.

Did you unplug the ABS sensors again?
Geriatric connectors need close attention!
Especially key engine sensor connectors.
Maybe you had a flaky connection at the ABS connectors?
Clean connectors with a toothbrush and isopropyl alcohol 90% and use Penetrox-A. Never use solvent on connectors, it can kill bullet connectors.

Good luck, Bill
