When Cold Start, the engine is reving 0-1300rmp
Hello!
I need a little help..
There was a MAF problem with my car: bad smelly smoke,lot of fuel usage..
I replaced it with a new one, not Bosch but work perfectly.No smelly smoke,normal fuel usage.
But, when i did this it was 10celsius..Now more likely to -5celsius.
When i start the engine a problem comes out,engine revving,and yes Sometimes fall down to 0RMP and back again to 1300,and 0,and 1300,and after a while,if the engine not stop, everything is alright.
But when i push the accerlator pedal a bit to fix the rmp to 1500 for a minute,everything is ok.
When i change gear when the engine is cold, P to R the engine stop sometimes..
Very strange to me..
Please somebody help
Thank u guys!!

Try disconnecting your battery by 12 hours+ this procedure reset all adaptations (fuel/air, trans) next day start the car but NO DEPRESS THE ACCEL PEDAL BY ANY REASON. the car would make a new adaptation an all will be fine again (if your new maf have a good quality) cause we here try lots of MAF's and no one works good.. Only the OEM or bosch make the car start and works fine. No other.

Thank u for ur massage,
After when we did this procedure, we delete all problem with STAR DIAGNOSTIC, there was 5 Big F( i think failure) and 3 small f. After when we delete all these,just the xenon automatic leveler system was the failure, little f. i know this problem(xenon)
The MAF sensor before delete was big F, and after when we delete it, not comes again.
i think this could change the battery take off method.
new symptom: When i go with 50km/h my leg on the accerlator pedal, not thortling,just stay on them and keep the 50km/h speed, and the cars RMP still jumping and the car is shakeing.
good quality, my shop told me that. But i have now a bad feeling about this shop...

Nope. Reseting the fault codes via Star Diagnosos not erase the adaptations (EGS and ME) but if you have the star diagnosis tool you would erase the adaptations to start a new one in ME/CONTROL UNIT ADAPTATIONS/ADAPTATIONS/FACTORY INITIALIZATION. and in the trans you need to go for EGS/CONTROL UNIT ADAPTATIONS/ADAPTATIONS/ERASE ALL ADAPTATIONS. this way your car start new adaptations for trans gear and Fuel/Air ration.
Easy way: Disconnect negative baterry for 12H+, after, connect the star diagnosos tool and simply reset all the fault codes (remember to initialize the steering angle sensor lock to lock and normalize all your windows/roof
Hope that help

I will watch for the EGR valve, yesterday i use the kick a lot.. and i think now its getting better...So maybe the lot of city driving,the egr getting carbonized cause the lot of smoke..
What will i do: i will clean the EGR valve,with brake cleaner spray, after WD40 to lubricate it,I will do this 12h+method,change the plugs,and wires,and maybe replace the outer temperature sensor.
