hey everyone. So for the past couple of weeks my car as been going into limp mode and feeling under powered... before i had it plugged in i've had all the sensors off cleaned.... the power came back!!, 3 days later limp mode again . injectors are new only 2000miles on them so i presume thats got to be checked off the list?. I'm thinking its the n75 valve but if anyone can shed any light before i start spending here and there that would be appreciated. Thanks all
