car misfires

[165_M3]

i got the codes:

p0128 <-- possibly thermostat and temp sensor? i got the increase emissions

p0300<
p0301<<<
p0302<<<<
p0306<<<< Coils most likely?
p0307<<<
p0308<

another thing is that the car would sometimes go into limp mode when im creeping along at lower speeds like in a drive through. but when i turn off and turn on the engine... it kind just resets. and all of these codes would just go away after a few drive cycles. then would just go back on again.


thanks all

i had a bad tstat and or sensor, it only gave me a check engine if i start the car and drive without warming. sometimes the car would buck wildly if i drive too aggressively for the first block. when i checked the tstat i found it to be stuck open. i could never understand how the car knows my tstat was broken within a block of driving.

This thread has all the error codes

i have researched that it could be

-SAP pump + EGR valves
-the ICV
-Throttle Bodies
-Pre-Cat O2 Sensors.
-or coils
