I'm trying to track down a sudden lean condition I get on the spray (as in, < .100 O2s). It never used to do this, and it doesn't do it N/A, so I'm figuring it's probably the fuel solenoid.

Is there a HOWTO for checking/cleaning these solenoids? I'd like to give it a once over before I sent it to NX.

 

take the intake beellow off, ignition on, nitrous off, and spray that bitch. if gas comes out the selenoid is opening. you could take the selenoid off and make sure its opening all the way. dirt and crap can clog it up though.

 

how do you clean it though??

 

although i dont have a real answer to your question. id call nx or someone knowledgable on the subject. i would just use some carb cleaner or something of that nature. i replaced mine last season though...for 70 bucks...i figure its worth it.

 

i think it would be better just to buy a brand new solenoids. safer.

 

There's a little tool you need to open it up, then it's pretty self explanatory...just inspect it and clean the seat if debris is present. A bit of carb cleaner and a q-tip works great.

 

Just like someone said you need to purchase a special tool that has two little tabs designed to fit into the two little dimples found on the top of the solenoid coil. Once you remove the nut that holds down the solenoid cover you will see these two dimples. From that point just unscrew the coil. Most nitrous companys offer rebuild kits for solenoids. These rebuild kits are cheap and easy to install.

Fun think is most people don't realize that a solenoid will wear out and is recommended that it be checked or rebuilt each year assuming nitrous use is offten.

 

and how much for a rebuild kit??

 

The solenoid rebuild kits run around $35.00 to $40.00 depending on the solenoid you have.

 

that's cool.

yeah, for safety sake. one should rebuild his solenoids per year.
