Hi...

I think my 1990 300zx (non-T, bonestock, MT) is running too rich, I smell fuel not being burned properly.

I was hoping for someone to point me to the right thread, I've looked and searched the Z32 forum and cant seem to find the fix.

I tried playing with the two adjustable screws on the side of the upper intake manifold (drivers side, near the firewall) but those screws lowers or increases the rpm at idle.

Please help. Thanks.

 

Consult the FSM, also not guessing at all is better then guessing when it comes to cars. Especially when you have absolutely no clue what you are doing. also smelling gas usually means you have a fuel leak somewhere, especially if you can smell it in the cabin.
