For most 94 and 95 3.8, you canīt use the paper clip trick to pull out the codes by flashing the CEL. I guess your code scanner is something cheap for 25$, and is working the same way, trying to flash the codes out. You need a more sofisticated scanner, that can read the 8192 baud OBDI data stream. You can also get an interface, (build it yourself or buy it) and use software from
www.pontiac-transsport.de
in a laptop.
With this software you can read out more data from the engine, tranny and the ABS system, and not only pull out the codes.
