Ok , sounds as though cleaning th tb is a good place to start.. Its a little hard to tell if its been tuned, as the actuator is stuffed and it hits the overboost cut. All looks standard. Bought from a dealer in brisbane, they had no idea. And it never stalled till afew days after I got it home.. Really only was able to boot first gear and it didnt cut out, as it was wet and had an old guy sitting next to me. wasnt till the drive home that I noticed the massive boost and it was cutting aroung 3k... Its a 6 speed manual and has 120k on the clock, motor sounds nice and quiet. Hope I didnt buy a lemon....
