Hello BMW World,
Completely new to the e46 and the DIY scene.
For a week now I've had this weird loss of power when applying low pressure on the Gas Pedal, when I try to full throttle it goes up, and when it comes down starts to lose even more power until it gets back up to normal on its own.
I've diagnosed the car with INPA and it gave me a misfire on cylinder 4, that's where the DIY in me started diagnosing even further. Tried the simple ignition coil test to see if the problem was in one of those 6 bad boys, and everything looked fine. Then I went ahead and changed the spark plugs, the old ones were for the replacement for sure, and then I started to experience a bit of an engine improvement idle.
So I tried the car and it didn't bring any code back after the changes, but the loss in power stayed there. Wanted to check on INPA and the live status on all the cylinders while I rev the car, what caught my eye is that cylinders 4 and 6 for some reason after I rev the car upon rev them stay in the normal green zone, and when I stop the gas pedal when the car goes back to normal these two cylinders start to misfire or in other words, they bring the data in the red zone.
I'm applying a screenshot when it did that only on Cilynder 4, and do keep in mind this is on idle after I went full throttle on the engine, but it did that once or twice on Cilynder 6 also and even they went once in the red both 4 and 6.
Sorry for the pretty simple explanation, I'm not that good, but I am looking to improve.
Thanks for the time and effort in advance.
