Barnstormer Posted February 8, 2012 Share Posted February 8, 2012 Hi, just wanted any advice re a small problem I had recently. Whilts driving along quite normally mid 2k rpm got the red warning light come on for about a second or so. Car drove normally and no other abnormal indictions/lights. Happened 2 more times over the next 10 mins as above then fine. Drove car about 2 hrs later and warning light came on again this time for about 8 secs and car lost power although kept going, v poor throttle response and slight hesitancy. Also got a small backfire/pop from the exhaust. Light went out and car drove normally again! Got home and did diagnostic check. Error code 31 only - Air flow meter circuit. (NB - battery recently disconnected as charged it up so is very recent code) Checked out the air intake temp sensor. Results: 2 dec c - 4.4k ohms 18 deg c - 2.7k ohms 90 deg c - 350 ohms. They look fine to me. Refitted IAT. Re-set ECU. Check codes and none present. Took car for a further drive, no repeat of warning and checked for error codes. None showing. Seems to be a one off but should it occur again where should I start to look? Note - have eManage Blue(inj & timing harness + MAP), RLTC and Blitz DSBC Any ideas appreciated.
