Hey, Sorry for my english. I bought old 626 few months ago, no service book etc.. I have this problem: When i star the engine, when its cold (I live in Finland, so I mean -10C ->), it does not start well at all.. or it starts but engines rev-sound is VERY poor and it some time shut off the engine.. In nordic countrys/russia etc we use electric heaters, witch heat up block or coolant. The heater do not help. The problems stops, when the heat-meter starts to rise. I have serviced my car in Bosch/Denso-workshop. They adjusted the diesel-nozzles, and checked the glowplugs etc. After that they put transparent lines for fuel, but there were no airleaks. They said the final diagnose could be Diesel-injection pump, but the new one could cost too much, so they dont even bother to think about it more.. My dad said, it also could be egr. I try to clean the egr (can you help me with that?) and after that I could consider that pump. Do you have any other ideas?
