Unknown engine problem ????

Hi,

any Idea is welcome

anyone had this before ?
My engine started up, hesitating, then nearly shutting of and after a minute running normally

now when I accelerate the engine follows the pedal but with delay
I didn't try to drive yet, only in 1st gear and reverse
same problem, like no power and long delayed

I just had my ecu reprogrammed also removing abc for coilspring
maybe I disconnected something or it might be electrical

no codes in DAS

weird

I'm also having this problem as well at pmercury. I have no code so check engine light as well, but I'm suspecting that it might be the throttle position sensor in the pedal, but I could be wrong. I switched back to OEM paper intake filters and will be cleaning the MAF sensor soon. I have 110k miles and this problem occurs on and off on 2003 CL55 as well. I'll let you know if anything changes for myself.

So not the lambda's, not the harness, not the plugs
just the ECU bugged, maybe a bad chip soldering
ecu was reflashed again and the beast worked again
lot's of worries for nothing finally
the beast is awake again !

tuesday I have a specialist adapting two Ferrari 500 v12 mufflers on my cl
i'll post a video for the sound
