Moin, moin I have a problem with my Volvo, this find every now and then to jerk, no longer took on gas and then went out some times when he did not catch himself anymore. After about 1min standing he ran again quite normal as if there were nothing. Now I confessed from work to go home and on the highway with 120 kmh he went out without warning and since then no more. If I try to start the car again, only the starter runs over. Volvo 850. 2.5L 170Ps. 1992Bj 165,000 Km. Vllt. do you have an idea what it might be, can I find out otherwise if I have a piston eater or something? Greetings
