I did it with the "pedal dance" and with the obd II scanner as well, and yes the actual valve did come with the oem valve covers

Yes, I did the relearning as per method but didn't fix the issue. Usually is idling at the rights rpm (around 700) but the hiccups and shake are constantly present. The stalling is not happening frequently, probably less than 5 or 6 times in an year but surely is something

Hi everyone, after being in this forum for ages and reading everything I could to get the best information and tips for my '03 v35 coupe, I finally decided to sign up to this nice and helpful community. I hope I can find some good advice for my problem 😁 In the past year I've been having a weird issue, my car (only at idle) has a little hiccups/shake every now and then and occasionally (just before nearly stalling) all the famous lights from the dashboard pops up. The car almost shut down (the radio turns off) but straight after it continue to idle. So far in the last year I've replaced (all oem): - Both upstream and downstream o2 sensor - Ignition coils and sparkplugs (2 years for the coils and less than 1 year for the ngk sparkplugs) - Both camshafts, Crankshaft, Knock sensor - Pcv lines all around - Maf sensor - Rocker cover and gaskets - Cleaned the throttle body properly - Aftermarket exhaust with high flow cats from kinetix - All injectors Apart from all of this I do change oil and oil filter every 5k and air filter regularly. I did a smoke test to be sure that there was no vaccum leaks all around, I honestly don't know where to look or what could be! Thanks in advance for your help, and sorry if is not the right way to post but I'm pretty new on this things 😅
