Alex smith Posted June 29, 2020 Share Posted June 29, 2020 Hi guys, got a stage 1 map done on my 1.8T AVJ engine but misfires when it hits boost, anyone got any ideas? The guy that did it says it needs all new coils and plugs but I’m not sure if he’s messed the map up and says this to cover his !Removed!... please help Quote Link to comment Share on other sites More sharing options...
Magnet Posted June 29, 2020 Share Posted June 29, 2020 Hello Alex, Sorry to hear of your issues. Can we take it you renewed the plugs, air filter etc. before getting the car remapped? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
Alex smith Posted June 29, 2020 Author Share Posted June 29, 2020 Hi Gareth, the plugs were put in a day ago when I did the full service so we had no problems with the map, the air filter is a mushroom filter and I have cleaned it out thoroughly, but my coils are old and haven’t been renewed. So I’m assuming if anything they’ll be the problem. Just found it a bit strange how he only mentioned it after the map was programmed and after it started misfiring not before like you would expect. thanks Alex Quote Link to comment Share on other sites More sharing options...
Magnet Posted June 29, 2020 Share Posted June 29, 2020 Thanks Alex, Sounds like you did what was good pre mapping preparations. Looking at it logically, the only thing which has changed is the mapping, so.... Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
