Trx 33 Posted March 3, 2014 Report Share Posted March 3, 2014 Engine code AUBI've just serviced the engine - new spark plugs, fuel, air, oil and cabin filters, topped off with shell helix 5W40 oil, i've also flushed the fuel system with red line fuel system cleaner and have been running it with premium JET fuel and Shell V-PowerI have removed and cleaned the EGR valveReplaced coil packReplaced HT leadsReplaced throttle bodyThrottle body aligned via VCDSNew batteryNO FAULT CODESProblems:The car doesn't start brilliant - turns over quite a few times before it fires upThere seems to be a flat spot when accelerating around 2k rpm sometimes, where it feels like all engine power just goes then comes back a moment laterLingering when the revs are coming downLag when revving - on my 1.4 non sport you can repeatedly bash the throttle and the revs will correspond. On the sport, if you bash the throttle the revs just mush around with no definition to themThe car is always noticeably smokey out of the exhaust regardless of the weather or how long the car has been runningThe car really struggles past 90mph, especially in 5th gear and if i'm giving it some, however it will happily cruise up to and past that speedIt seems as if when you have the accelerator pedal fully depressed and then ease it back a bit the car picks up a littleI know this engine is renowned for having throttle lag issued but it just seems that this is an abnormal amount of lagIf anyone has had any of these problems and has managed to rectify them or just has any suggestions ill have a look into them as i'd like to get this car running 100% or near enoughI've put a hell of a lot of effort (and money) into this car getting it roadworthy and running and ill be damned if i can't get it at least 90% Quote Link to comment Share on other sites More sharing options...
Dblock Posted March 3, 2014 Report Share Posted March 3, 2014 I thought sounds like your tb might be a dud but that's been changed. A shoot in the dark but is there anyway to test the accelerator pedal? My sport was always smokey but it was white smoke but not just after you switched it all the time. You notice it more due to the centre exhaust. Quote Link to comment Share on other sites More sharing options...
Trx 33 Posted March 5, 2014 Author Report Share Posted March 5, 2014 I've monitored the on VCDS and it seems to be ok, ill have another look when i get a chance though.I'll try to get a video of the lag at some point too Quote Link to comment Share on other sites More sharing options...
cal_j Posted March 20, 2014 Report Share Posted March 20, 2014 Did you manage to sort this problem? Iv just bought a lupo, same spec and I'm experiencing similar problems, again ht leads, throttle body, coil pack all Bren replaced but still has problems. Mine also refuses to rev over 4300rpm....
