Kharmon Posted November 8, 2016 Posted November 8, 2016 Hi guys just installed the stillen gen 3 intake. booked it for a tune on the 21st .The only problem is my check engine light is on any idea why ? The car seems to be driving fine . Could the maf sensors need cleaning ? If so what do i clean them with ? Thanks in advance Quote
Kharmon Posted November 8, 2016 Author Posted November 8, 2016 Check the code, could be anything. It came on as soon as i installed them like with in 30seconds of running Quote
Ekona Posted November 8, 2016 Posted November 8, 2016 Okay, so likely you've got an air leak or a broken MAF or damaged wire or knocked the throttle body, but even so it could be anything. You need to read the codes, else it's guesswork. Quote
Snjur Posted November 8, 2016 Posted November 8, 2016 Have you played with throttle flap? If so that could be reason. If you don't have diagnostic tool on hand you can do a throttle calibration by yourself to eliminate that Sent from my SM-G850F using Tapatalk Quote
Kharmon Posted November 8, 2016 Author Posted November 8, 2016 All fixed just had to disconnect the battery and the reconnect to reset the ecu went for a 20min drive and its stayed off 😀👠Quote
Ekona Posted November 8, 2016 Posted November 8, 2016 And now you have no idea what the code was, could've been something important. Why did you not just get it read?! 1 Quote
sipar69 Posted November 8, 2016 Posted November 8, 2016 Ten quid wifi dongle and a download of the free OBD Car Doctor app has been one of my best investments. It correctly diagnosed the common issue with HFCs and the check engine light on the Z and a faulty sensor issue on the Aygo. 1 Quote
GMballistic Posted November 8, 2016 Posted November 8, 2016 And now you have no idea what the code was, could've been something important. Why did you not just get it read?! I have to agree with Dan you would have been much better checking the code Op just to be certain as to why it came on. I mean if you knew for example it was caused by a secondary O2 sensor fault after fitting HFC's or De-Cats then by all means reset the ECU and wipe the code but without knowing is a little haphazard. Hopefully it was nothing serious. Definitely worth following sipar69's suggestion imo. 1 Quote
Kharmon Posted November 9, 2016 Author Posted November 9, 2016 I read on the american forum that it happens if you dont disconnect the battery during the install which i never .so dont worry the ecu just needed resetting. Will have a look in to getting one of them wifi dongles though sounds handy to have thanks👠Quote
