So I was driving today and the car felt like it was starved for fuel and wanted to stall when driving in any gear. I would push on the accelerator and there was no power. Car has no check engine light and a scan didn't produce any codes. When I turned the car off and started it again the problem disappeared. Has anyone had this experience or know what it is? My car is a 99 m3 manual with 92k.
Could have just been a glitch,
but if it starts to reoccur,
I would hook up a FPG to the fuel rail,
and note differences in readings-as fuel pressure should remain at or near 51psi.
Sometimes the check engine light does not come on right away. When one of my coils went bad it wasn't until the next day that the light came on.
I address the CEL when it appears,
but I take notice of anything that I can >SEE,HEAR,SMELL,
and not wait until a CEL decides to notify me.
BMW Error codes are detected and can be stored as pending codes by BMW modules,
before any warning lights become visible.
Just because no lights-doesn't mean no codes!
IF an error was detected, there will be an error code stored.
Fuel pressure itself may not throw a code, but its effects will.
Where do i hook up the FPG? is there a port somewhere?

Did you have less than a quarter tank of fuel hit a corner pretty aggressively and starve the fuel pump?

It was done by the previous owner in the last six months but it might be worth changing. I bought the car a few months ago and it has run flawlessly up until one event last tuesday and then yesterday. This is my second m3 vert and 3rd e36 m3.
The weird part to me is that turning the car off and back on made the problem go away.
Is it possible to have a crankshaft speed reference sensor code but the check engine light isn't on? I can't get any codes when scanning but the shop says it did. Any ideas?
Depends on type of scan tool used,
Generic OBD2 or BMW specific scantool/software.
