Maybe TCS or problem with electrical throttle body. The gas pedal was time by time hard (went in emergency...) But engine would not go well anyway.. so maybe bad SDI or something other. I had it at one guy who repaired SAAB for a long time, he tried lot of things, but one day he told me that he dont know where is exactly problem and he have not time to find it, so he towed saab to my garden and the car died there :( but some spares has been used to brothe's 900T-I :)
Ok, that probles has killed a lot of 9000. I haven´t try too fix a car with that problem myself but I think that the easiest way is to get rid of the whole system. The problem is that the system is involved i a lot of other systemes so you have to change engine cable harness, APC/DI/LH boxes, ABS components etc.
