If your 87 900T is misfiring at higher boost pressures, try adjusting you plug gap. I had an 83 900T that came from factory with a plug gap of .026. When I got an 87 900S 16V, I used a plug gap of .028. I also used the .028 gap in my 87 9000S. Now I use Bosch Platinum +4 plugs and I am very happy with them. The Saabs with DI ignitions pretty much have to use the NGK plugs, although some have been able to use Bosch Platinums in the non-turbo cars. If your gap is too wide, the boost pressure could be killing the spark. Check it out. Ken Washington 87 9000S 87 900S 83 900T
