Good morning we have in the workshop a JEEP RANEGADE TYPE BU ENGINE 1000 12V TURBO KAT PETROL 88KW REGGA FS078YG ENGINE 55282151 The car in cold start about 1 time a week starts with two cylinders and gets error missed ignitions and P1471. Then it starts running on all three cylinders and goes well for a 7 days if we reset the error does not reoccur for other days. the errors of lack of ignition are sometimes combined with error voltage valve control cil 3. sometimes takes only error P1471. We have noticed that the battery voltage during cold starting drops below 9 volts as it is star stop.Can you give us any indication?
