Hi,

i had fit siemens 55, lambda and closed loop chip and i have some questions:

- on bosch injectors, you have a plastic cap on the bottom of the injectors, does i need to fit one on the siemens ?
- i had fit the lambda sensor on the standard connector of my sierra 4*4, how verify if the signal is good ?
- on my l8 , i can turn clockwise and anti clockwise infinite, it's nomal ??? do you have a stop when you turn clockwise ?

regards
