BMW 335I E92 IDLE SEEMS NORMAL, LOW RPMS ARE OK.When I floor it the car shuts down jerking, bucking idle surging dash lights. I turn the car off and restart back to normal idle floor it again and same cycle. Had code po122 one time erased it didn't come back but still have the problem, only when I floor it. Any suggestion please...thank you
How old are the spark plugs
I'M not sure Only had the car for a year. Always work on and owned BMWS never nothing like this. Wouldn't I get misfire codes? Thanks
If the plugs are bad they wouldn't idle be crappy? and would they only fail wide open throttle? I was thinking throttle position sensor going bad. All though a tune up wouldn't hurt. Just need the car now. Thanks for your help

First step is to pull codes with a BMW-capable scanner. Generic is unsuitable.
Are you gonna eat that?
DA I'm the idiot I am using a generic scanner when I already have BMW scanners and software. Going to make the car do it again and pull the codes Thanks sucks getting old
Of course I floored the car several times and things are fine????
Did you scan and read any BMW specific fault codes?
