120i Stall When initial Accelerate

Post by Adejul45 » Tue Mar 20, 2018 2:04 am

My car is e87 120i AT 2005
Its been years that few times in a week the cars been stalling between idle and initial accelerate... so when i want to put on gas to accelerate, the rpm instead go up, it goes down to 600- rpm and if i continue to gas on the car will be died.. i need to letoff throttle 2 second to stabilize the rpm and its gone then, mostly stall like that in warm engine and hot condition at 12.00am
Have done
O2 sensor 4 pcs replaced
Cleaning fuel injector
Change sparkplug
Clean and mix up position of ignition coil
Clean throttle body
Change air filter
Change valvetronic motor
Change eccentric valvetronic
No Fault Codes

And there is unique problems, when i use Ron92, error 29f5 will appears.. delete, and errors will occur again in thousand Km.. the error persist before and after changing o2 sensor

Then i use the Ron 90 and 29f5 errcodes never occurs again..

Please help about the stalling issues.. it can be fatal if stalling happens when on U Turn and etc...
