Hello! I’m new here and looking for a long time I didn’t find any suitable ones, maybe you can help me BITTE! I have a V70I Awd 193Ps bj 97 but it was converted to normal due to defective angle gear, the previous owner had the chip of a V70 T5 inserted and changed the turbo since I had it he has the following problem: when it runs cold he jerks and takes hardly gas, and when it is warm and I push the pedal he pulls through and does not want to get on tour so properly, it seems almost as if he would not want the area where he doesn’t want to because at about 4,5t he catches himself again and then gives it really material but also not always it is really sporadic. Tubes are all, I have tried already with a sports air filter the problem was still there but it comes to me as if a little better. There are new Z.kabel and kerzen as well as it is not always sporadic. Tubes are all, I don’t want to use it again?
