Hi, recently its been colder and on start up the car goes to high idle at around 1100 rpm, after about 10 to 20 seconds the engine begins to missfire, it drops in rpm and then recovers for about 30 seconds and then is stable at idle. It doesnt sound great and I have no codes active on the car, scanned with OBD and nothing seems to be out of the ordinary, I do have a trend where I recorded the fuel pressure and it seems to be consistent, it increases in pressure after 10 seconds then begins to missfire, any help would be appreciated. If you have any suggestions Im happy to look at any data on OBD, cheers.
Link to trend of fuel pressure, the missfire is obvious on the graph
