P1115 ,p1119- O2 sensor heating below threshold.
Bad O2 sensors, wrong sensors for your car model, mis-wired sensors, damaged wire harness. You currently have no working O2 sensors so no monitoring of your mixture. This can damage your cats and potentially your engine over time. Probably the cause for misfire also as the DME is blindly attempting to control mixture.

Also there are several different MAF sensors so you would be wise to confirm the part # for the one you installed and make sure it is the right one for your car year/model.

Time to knuckle down and retrace all recent repairs to see where things went sideways. Good luck!

I had recently cleaned the throttle body when i replaced the MAF i also did that one mod a pedrosgrage.com with the air intake. I figured, wile its off there might as well change it. There was no sign of oil in the intake/ throttle body and the old MAF didn't look bad at all... The new MAF looked exactly like the one i pulled off the car same bolt pattern, and plug spot. It was also a Bosch as was the one that came off of it. As far as Miswired sensors they were straight plug and play they were slotted so they could only go on one way so highly doubt that is the case.
I have to say I'm starting to suspect the ECM or computer myself..
If y'all have some pics or description of where i can find the AOS ill definitely take a look at it.
On a side note do you think the car could have jumped time??
I have to work a 24 tmr but after that ill have a 48 off so ill take a look at the plugs then.
ill get myself a code reader as soon as funding permits... I still have to replace a rear tire. (had a blowout the other day so now I'm riding on one new and one old one)
Thanks for all the help guys i really like brainstorming with y'all

So I went to take the car to momentum motorworks in Birmingham they specialize in Porsche and BMW. I made it about halfway there and the car quit on the interstate. It had a serious decrease in power and the check ingine light started flashing. When it started flashing the car would run ok then as soon as it turned solid it would loose power and barely move! So I pulled off the road and called a rollback and got them to take it on up there. So the guy calls me a couple of hours later and tells me my oil seprator is bad and it was going to be $405 parts and labor to replace it and that it wasn't a 100% guarantee fix. I was very currious. Am I getting ripped? I've never herd of an "oil seperator" does Antony know anything about this thing??? Is it the same thing as the AOS?

AOS = air oil separator.

btw, when your car starts acting up like that, don't drive it. you can do a lot more damage ($$$$$$$$$$$$$$).

if you wind up needing the coil packs, PM me. i have a full working set you can have nice & cheap.


EDIT: one more thing. $400 parts and labor to replace the AOS is fair.

[Porsche_Baller]

Great thanks for the help! If I need coil packs I'll deff let you know. As soon as it started running that bad I pulled off the road.I wasn't sure if that was the same thing he was talking about because he just called it the oil seperator:\

Im not sure the AOS would cause your problems.

Sounds to me like something is disconnected, maybe even a coil pack. Are you 100% certain you put everything back together right, or maybe didn't knock something loose?

You know, I have had a brand new Bosch o2 sensor be bad right out of the box.....

Sounds fair to me, too.
Also, get the mechanic to remove the spark plugs and crank the engine over several times before he tries to start the engine back up after he replaces the AOS.

If there is enough oil in one of the cylinders, it can hydro-lock the cylinder, and break things you really don't want broken.
