Help misfire
« on: July 11, 2019, 07:00:13 PM »
Hi all so I've finally got my s3 injectors for my ko4 conversion, can was running fine for the last month or so. So sunday night I removed the inlet manifold changed the injectors which have been tested by r tech and been give the all good fitted the run flap delete bigger fuel pump internals and drilled out the fuel inlet pipe to 5mm now drives fine plodding around but when wide open throttle starts to misfire at around 3500 rpm havent looked at codes yet but wondering if it because it need mapping now as feelings all over the place compared to the standard bwa engine or are my injectors had it :confused:
