NGK spark plugs?
96 sc300, have anyone used NGK laser patinum spark plugs (BKR6EP-11)? I'm having misfiring cyliner 4,5,6. I don't have EGR valve nor EGR modulator. Idel is very bad on 700rpm under.. can anyone help me?

When you go +/- 1 from the number thats just going with colder or hotter plugs. I forget exactly which is which but I guess he wanted to try and run colder? or maybe hotter plugs.
sc300Super: uummm Check continuity of the wire. Also check the cap and rotor of the distributore. It may have gone bad already.
Good luck.

The cap and rotor buddy. Make sure those pins are good.
Heres a picture... FYI, not SC. I just pulled it out from google to make a point. +1 with 24boosted. Maybe you crossed the firing order of the wires as well so check that too.

Are you throwing a code?
If the car was running fine prior to doing this then either those plugs are incorrect (guessing they are pre-gapped so that counts out gapping issues) or else you messed something up on your install.
Pull the new parts off and start over.
