Fellow Nobel Ferrarist, Do you have to pull the throttle bodies to access spark plugs 3, 4 and 9, 10? I can't seem to snake out the respective ignition wires otherwise. Any cautions working with the throttle bodies? Cheers, Chris
It’s a fidley wiggle but it can be done. They bend. Seem to remember opening the throttle to help gain access.
Scowman, Thanks a ton! Love the description. Fatbillybob, An honor having feedback from you, sir! Definitely the approach I will take. If you ever venture up to CT, look me up sir. Will treat you to some libations on me! Cheers, Chris
Also, if you don't have the Hill tool to pull the plug boots, invest in one. The boots like to mold themselves onto the plugs and you can easily rip or tear the boot getting them off if you don't have the tool. AMHIK. I ripped a boot even with the tool!
Cribbj, Is that the same tool as the 355 lead removal tool? https://www.ricambiamerica.com/prt-01-f355-spark-plug-lead-removal-tool.html Thanks, Chris
Success. Just sharing some notes here. 1) Remove Tube from underneath the intake manifold leading to the Fuel Vapor Filter. Removed retaining bolt at front of manifold, loosened tiny clamp and plucked it out. 2) Freed electric cable just aft of the throttle body routing under the intake manifold. Left it connected, but unclipped it from retaining clips so it moves. 3) Removed four screws for throttle body (along with holder for electric cable above) Did not fully remove throttle body. Those damn mechanical cables underneath scare the crap out of me! 4) Removed the two bolts holding the support for the mechanical throttle body cables (they look like throttle cables, but they seem to synch the two throttles) so the throttle body can move easier. Did I mention those scare me. Small hands and a lot of "fidley wiggle" got the two middle ignition wires out. I had loosened some other tubes and disconnected the intake routing from the airbox, but in hindsight those were unnecessary steps. Its worth noting that the wires give a false positive seat feel. Needed to use a good amount of direct pressure (used hammer handle) to get positive click. Love wrenching on this engine, but plenty of mysteries abound with it! Thanks for the pointers...
