It’s weird how it was running fine replaced a water pump and now it’s missing. I’m a little embarrassed to say what we have replaced, spark plugs ht leads cap rotor ignition module coil air mass meter fuel pump. When this all started I was convinced it was an earth fault I’ve checked the basics battery earth motor earth an auto electrical friend started a bit of a probe and found the temp sensor not working correctly making it run lean replaced sensor. It’s not a case of money I would like to find the fault I can’t be the only person that’s had this fault. Most of the time you think it’s fixed drive 20 30 km and all of a sudden it back. HELP HELP
