So where exactly is this fast idle thrermo valve, I have a chipped ECU and my idle starts at 3k then drops to 2.5 then to 1.5 and then will bounce between 1.5 and 2.5. I was reading some old threads and it said to adjust the cream colored spring on the FITV.

 

hmm comes on the h23 but not 22, i found it no worries

 

Its probably the tune more than the valve but good luck with getting it taken care of.
