I am about to take my 1995 Maxima GXE in to have a full throttle service done: Extensive cleaning of the Fuel Rail, Injectors and Throttle body.

I have been told that to do this, they connect through either the PCV Valve, or the Schrader Valve. Do Maxima's have Shrader valves on the Fuel Rail? I want to make sure they connect where the Injectors will be the first thing that get cleaned.

Can anyone offer any insight as to where I should tell them to connect to ensure the injectors get hit first.

Thanks in advance.
