Endplay check
http://www.angelfire.com/pa4/awdcrankwalk/
Crankshaft endplay 0.0020 - 0.0071 per AllData for 96 AWD Turbo
Could be wiring issues also, so checking for crankwalk without tearing things apart might save you some time.
I should be available after Wednesday this week in the afternoons if you want help.
