sounds like EU5 injectors and those r about 100 a piece with new seals and all. Use "injector determination" in ISTA to see which injectors you need. That is correct, without a cel most dealers will tell u, its fine lol. Exact opposite of what they're supposed to do (I think)ĭid this rough idle happen after the downpipe install? Pre Cat O2 sensor barely moves and post Cat O2 sensor cycles between. Reason I ask about position is because they are behaving like they are in the incorrect position. Are these the correct positions ? They are connected properly but are they in the correct position on the Cat. The Pre Cat O2 sensor (brown marking on connector)on left in pic and the Post Cat O2 sensor is on the right. I'm getting misfires in the misfire counter after every warm restart. N55 engines r known to run a bit rough on hot restart for a few seconds Oem coils.ītw how long does this rough running idle last? Have since changed plugs and coils 3 times with new ones and no resolve.Oem gap. Open used for connection network adapter properties, then Internet Protocol Version 4 (TCP/IPv4) properties, then enter 169.254.1.1 for IP address and 255.255.0.0 for Subnetmask. This whole rough idle thing happened the day I did new plugs and coils. using bmw rheingold ista with bmw enet cable 1.

My dealership sucks at troubleshooting a car when no CEL present. I was kinda hoping my CEL would come on but I guess it's within threshold for now. Just to confirm, double check to run the vanos system test, i know u mentioned u did the relearn. There isn't any injectors tests i know of in ISTA. N55 fuel pump and injectors r pretty reliable.Ĭould start by looking into ISTA into fuel pressure at the rail is where it is suppose to be.įrom there i would start swapping injectors or putting in new ones to see if misfires go away.
