Grounding wire locations?

[90AWDTSi]

Hi im having an issue with an intermitent short to the mfi relay. the car will start and may run or will start and begin to have the rpms go from idle to zero and back and forth until the car dies altogether. i pulled the relay out and cleaned the contacts for the pins and the contacts themselves. im wondering if it could be a loose grounding wire? any ideas?

Idle air control, massive boost leak, maf not plugged in? If the MPI is not clicking on and off and the fuel pump is running I wouldn't look there.
