I wanna convert my City Vario but heard from my mechanic (and friends too!) that CNG conversion is not successful for City Vario (City Manual is OK !). Please advise as per your experience. Thanks and regards.
true!! to much issues with low RPM: breaks, accleration maintainance issues like fule sensor gets crappy every now n then and finally you'l get emulator disorders frequently.
Yes RPM dropping is the key issue..car turns off when u idle it
