sosolid Posted May 22, 2014 Share Posted May 22, 2014 hey guys so my glanza has a dead spot. when im at low rpm at like 2000 or lower and floor it, the car slows down like somethings pulling it from the back then boost kicks in and its off. ivd got decat blitz ecu magnecores. it started last year. when crusing at 30mph in 4th i can feel theres a misfire. changed coil pack 2. doesnt use oil or water. what can cause this because it started out of the blue and dont know what it is. please help Quote Link to post Share on other sites
akyakapotter Posted May 22, 2014 Share Posted May 22, 2014 Unplug the lambda sensor see if it stops Quote Link to post Share on other sites
richardc9052 Posted May 22, 2014 Share Posted May 22, 2014 Check for fault codes. If there arent any id check the fuel filter and throttle position sensor Quote Link to post Share on other sites
sosolid Posted May 22, 2014 Author Share Posted May 22, 2014 when i check for faults the engine light just lights on and off none stop so im guessing because its continuous theres nothing wrong there. it only does this at low revs and speed when the car is warmed up. when cold its ok. but at high revs its perfect. how do u check throttle position sensor.?

sosolid Posted May 23, 2014 Author Share Posted May 23, 2014 (edited) update guys. so i was looking through youtube and found a video of a guy who has the same prob as me. so jerky at sluggish at low rpm and is great at high rpms when boost kicks in. he found out the prob was the o2 sensor. >http://www.youtube.com/watch?v=bC5Vu_jrcJU Edited May 23, 2014 by sosolid Quote Link to post Share on other sites

richardc9052 Posted May 23, 2014 Share Posted May 23, 2014 The other option is to buy a wideband.. £150 delivered on ebay for an AEM UEGO and you can set that up to work as your lambda and keep an eye on your fueling. If you factor in the cost of a lambda it makes the extra not so much to have what anyone running boost should have.. Quote Link to post Share on other sites
sosolid Posted May 24, 2014 Author Share Posted May 24, 2014 ok so ordered a new lambda but doesnt come with plug. can i just tie the wires together and then use black electric tape to connect them with it? i dont have welding equipment. would that be ok. Quote Link to post Share on other sites

Chops Posted May 24, 2014 Share Posted May 24, 2014 My impreza does this, stutters a bit when you put your foot down before boost comes in. sometimes misfires on boost too, makes a hell of a bang lol. Quote Link to post Share on other sites
