Possible fuel issues

Installed the new fuel rail pressure sensor 140bar from finjector. Now I get a p2122 code saying accelerator pedal ckt low voltage and the car barely idles my ap will not clear the code. Any and all help appreciated.
 
Ok. So just for some info. If you plug in the fuel pressure sensor upside down" and it will plug in" you will get that code. New 140bar sensor and I'm getting 1700 or 1800 and some psi wot. Little backfires here and there driving. No cats. Maybe plugs will fix that
 
Well that's certainly better, odd that it plugged in upside down. I agree worth checking plugs now, some after fire rumbles catless would be normal

I'll get some new plugs this week and put them in in and order hpfp internals. Thanks for the help. Much appreciated.
 
One another thought, i read on a thread while searching for help with fuel pressure about getting rid of the annoying load up of fuel or the rough engaging in gear while shifting between gears... i cant find that thread again. does anyone know what Im talking about? I know Im not good at explaining this .
