Hi, I need a bit of help. Once my car gets nice and warm, it tends to stall when its at an idle. When i come up to a traffic light for example, ill shift down a gear and I can hear popping out the exhaust, and once im at a stand still the revs are up and down then it stalls. Its a turbo II, this has just recently started. I just moved from about 1000 meters above sealevel to 300 meters above. I though that might have something to do with it. My TPS is buggered, im certain that is not the cause though as it has been shagged for a while now. If anyone has an idea what this might be your information is much appreciated.
