Tighten to 20lb-ft https://www.hyundaiforum.com/forum/a...1&d=1300234993 Out of NOVA' instructions..... #3 -- leave the sensors plugged in and attached to the bracket,, just remove the 1 bolt that hold bracket to plenum (#10).. #4 -- remove bracket from plenum, unplug coil lead, and take all 3 coil out with harness attached when time come. Skip #6 and #7 #8 -- remove the rubber hose for at top of throttle body, remove brake booster hose, and remove the bolt "A" at bottom of throttle body.. then remove the 3 bolts holding throttle body to plenum.. look at my pics as to how it should look. |
2006 Azera Spark Plug Replacement
Thanks so much for the information. The instructions were easy to follow - great!!!

FYI, my instructions are from Hyundai servcie website and are "by the book" but sbr711 is a Hyundai tech who does this on a daily basis. He knows the shortcuts so take his advice on making the job easier.

When pulling the intake, should I replace the intake manifold gasket?
|
Yes, you should.

Thanks for providing the information for all of us. I am now ready to tackle the "spark plug" replacement on my Azera.
|
Great info, I'll have to change mine soon

I GIVE UP !!! How do I disconnect the AFS connector as shown in Step 1 ?? I have searched through both volumes of the Azera Factory Service Manual as well as looking through many posts on this forum but can't . There must be some sort of tab on the underside that must be depressed before the connector can be disengaged... but I can't find it. CAN ANYONE HELP !!! Thanks so much !
