What? Wow dude, welcome to the forums and all, but your question isn't very well explained, and you haven't shared any troubleshooting you've done, etc. Check out the FSM (found in many places), check out our guide
everything-you-need-to-know-about-the-z32-t508377.html , check out z32.wikispaces.com . For all these random connectors, probably try to share pictures. Ticking noise could be lifters, but it depends on how you define ticking, hopefully its not knocking. Maybe post a video for that. For idle problems, there's tons of potential issues, you need to do more troubleshooting, this is extremely vague. My advice is to break your problems up into smaller chunks, starting at the most important stuff.
