am i not seeing a DIY diagnostics and asking questions for help? wheres the most appropriate place opost such a thread? like the evap problem i am having right now

 

Assuming you're posting about a 2nd gen IS, you'd post your questions for help for that vehicle in the 2IS section https://www.clublexus.com/forums/is-...2006-2013-163/

For DIYs, check the FAQ/DIY sticky at the top of that forum before posting https://www.clublexus.com/forums/is-...iy-thread.html

Also use the search feature to narrow down threads that might answer your question. Searched for 'evap' in thread titles in the 2IS forum got the following result threads for example
https://www.clublexus.com/forums/is-...highlight=evap
https://www.clublexus.com/forums/is-...highlight=evap
