Flex Posted September 6, 2013 Share Posted September 6, 2013 Had this a couple of times now after it's been running for a while and say go for petrol, will start her up and fires no problem then revs will drop way low and almost if not will cut out. No engine man lights coming on at all at the moment. Bit damp today, possible factor? Any thoughts? Quote Link to comment Share on other sites More sharing options...
Neilp Posted September 6, 2013 Share Posted September 6, 2013 Maf sensor maybe? Quote Link to comment Share on other sites More sharing options...
Flex Posted September 6, 2013 Author Share Posted September 6, 2013 No management light though, thought it would have triggered? If I plug my reader in might it flag it even if EML not flashing? Quote Link to comment Share on other sites More sharing options...
Neilp Posted September 6, 2013 Share Posted September 6, 2013 Don't think so mate. Depending what system u have it sometimes shows pending codes. I don't think it will show a eml for the maf playing up either. Is there anybody close that u could borrow a sensor from to test it out?

Flex Posted September 6, 2013 Author Share Posted September 6, 2013 I'll run her up to the garage me thinks. Cheers Neil. On a side note thinking about getting a run around for the winter, how's the Swift? Quote Link to comment Share on other sites More sharing options...
Gudzy Posted September 6, 2013 Share Posted September 6, 2013 I had a similar problem where the revs dropped and it stalled a few times when I needed to restart the car after it had been on recently, so when filling up with petrol. I had the throttle body cleaned when the plenum spacer was installed and its not happened since. I seem to remember reading a thread at the time suggesting it was throttle body related which led me to getting mine cleaned. 1 Quote Link to comment Share on other sites More sharing options...

Neilp Posted September 6, 2013 Share Posted September 6, 2013 Yeah try a throttle body reset actually. Never thought about that Quote Link to comment Share on other sites More sharing options...
Flex Posted September 6, 2013 Author Share Posted September 6, 2013 I have had the battery disconnected too, so probably part of it, will run through the reset procedure and give it a clean. Quote Link to comment Share on other sites More sharing options...
Kylefly Posted September 6, 2013 Share Posted September 6, 2013 Mine kept doing this and stalled most times, cleaned the throttle body with a carb cleaner and it hasn't happened since! Quote Link to comment Share on other sites More sharing options...
Toon Chris Posted September 6, 2013 Share Posted September 6, 2013 +1 for a dirty throttle butterfly. Once cleaned don't forget to do an idle air reset or the reves will hover at 1.5K and do your head in! 1 Quote Link to comment Share on other sites More sharing options...
longsh07 Posted September 6, 2013 Share Posted September 6, 2013 Had this problem today (http://www.350z-uk.com/topic/75820-lumpy-idle-revs-drop-almost-to-stall/) Cleaned the throttle body and gave it a few good revs, problem solved.

Sam Mcgoo Posted September 6, 2013 Share Posted September 6, 2013 As suggested, try the throttle body reset, maybe it needs a clean. You can also try cleaning the MAF. If your still having problems in a couple of weeks, or don't want to try the above yourself, your welcome to pop over and we'll have a look together. I think I've got a spare MAF you can try if need be. Quote Link to comment Share on other sites More sharing options...
