85' EFI? If 4Crawlers suggestions dont work out, then I'd be suspicious of the EFI wiring harness. With it cutting out when going around a corner and the intermittant occurances Id guess wiring. Only because I experienced this with my 87' 4Runner. Would fire right up with starter fluid and run until the juice was spent. The EFI wiring harness leaves alot to be desired, all 4 injectors are connected via one really schidty butt connector mid harness that has a tendancy to ROT. This connector ties all 4 injectors to ground...on 85' no ground equals no gas. Check 4Crawlers list first then move onto the wiring harness.
