Ok, Heres my issue, My check engine light is on, been on for about a week, didn't have the money to have a scan, still dont really, had a friend that works at BMW scan it. here's the issue:
Original ongoing problem, CEL, eats fuel, and kind of (actually very) jerky in low to mid RPM's or during some shifting, some times not noticeable, sometimes neck breaking. ???
Somewhat of a new problem: Even after sitting all night, starting the car I have about a 50 percent chance of the oil temp being normal at the middle gauge, or going strait to max temp, staying there the hole time I drive, or have it go to normal after a little bit of driving??? the car usually smells like its going to explode form the heat, but even when temp is indicated normal, seems like it runs hot. What the hell is wrong with this crap, The car was (assuming from all the maint. records i have from the original owner, ) well taken care of, so what the hells going on now.
I have the gt1 scan codes in the car will go get them and post them, but have heard oh its the MAF's, oh its the o2 sensors, oh this that, well which is it, Im really getting fed up and might just wreck it and take the insurance money lol, I love this car, but this is frustrating, any help would be GREATLY APPRECIATED, I live in VA Beach Virginia, and if anyone local can help that would be awesome as well.
Here are the codes, from the BMW dealership:
They gave me a print out, so here it is:
(PAGE 1)
73 signal, mass air flow sensor, implausible recorded as 1th fault in memory.
Type of fault at 1the occurrence
the fault is currently present.
(OBDII code: p0101)

multiplicative mixture adaptation (part load)
bank 2 21.7 percent
note: values lower than 0% mean mixture leaning
(PAGE 3)
144 function, oxygen sensor control, bank 1 recorded as 14th fault in fault memory.
note: check oxygen sensor before cat. converter

intake air temp 55 Celsius
coolant temp 89 Celsius
multiplicative adaptation factor, bank 1 1.210
Have heard of several test to try, but cannot remember if someone can link to those posts or tell me, thanks.
Don't really have the money to blow on misdiagnosis so any help is appreciated.
Oh also I just got my oil changed at Firestone, and now i keep getting the check oil light, most of the time. I check it it usually is OK but sometimes low, engine compartment looks clean, so does bottom of car after a nights rest. this is really wearing me down thank you
will accept any PM's or reply, or txt's or calls at 850 776 3179, I live at NAS Oceana anyone nearby with a scanner??
Thanks for any input in advance.
