Again a new one with an old question. 🙂 I have a 98 ́ Carisma GDI/ automatic with now 75 TKM. I have the same problem as probably many here: irregular idle. I have read here the carbon blaster should help and the exhaust gas recirculation shut down. now my questions: 1. How long does it last? 2. Where do I have to/can I have this done ( Mitsubishi or free workshop) ? Am here in Munich. 3. The price read here often about 210 € , right? Or 4. Or can I do something myself? Would I be glad if someone could help me. Until then, Micah
