Yesterday I filled some oil into the engine (I got a low oil message)
and also deinstalled the vortex, maf and airbridge to be able to deinstall the nitrous nozzle which was the last Nitous part on this engine.
After that I reinstalled the Vortex and maf and plugged the little screw into the fuel test port (where the fuel line to the fuel solenoid was plugged in).
Today I started the car and after a few feet the car stumbled, then the check engine lite came on, off, on, off a few times, than the car pulled again like there was nothing.
Since then it does that whenever I start it. Just starts to stumble enginelight on off a few times and then runs like normal.
I have then the P0152 code and tthats 02 sensor Bank 2 sensor1 high voltage.....
So it seems I somhow run rich at the right bank and the car tries to compensate somehow and thatīs when it stumbles and the check engine light comes on, of,on, off.........
What the hell is that.
Did I damage something.
Can it be that I overfilled the engine (oil).
Iīm no rookie...I donīt fill oil into my engine the first time, but who knws.
Could that cause the car running rich.....and why only on bank 2.
Iīm very frustrated.....the car is at the mechanic now.......
Not to look at that problem, but to pull it because it will be sold.
Now what do you think, is the problem engine related (really hop not),
or what??
It worked perfect till I did what I wrote above and the next time I start the engine and go for the trip it does like I mentioned.
What the hell can it be??
Could it be the MAFT (it is set to 10% lean) to compensate for the #30 SVO injectors, but I donīt remember that I even touched it?????
Or can it be a unplugged spark plug wire or a damaged O2 sensor???
Only wondering why that happened the next day after I worked on it???? <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
Need urgent help please, so I can sleep at night.
Thanks a lot,
Michael

This what a P0251 says:Injection Pump Fuel Metering Control A Malfunction (Cam/Rotor/Injector)
It doesn't say anything about O2's in my book.
