[QUOTE="encasedmetal, post: 14671351, member: 80137"] hey everybody- I started up my newest setup last week and it has a high idle of 1700rpm and I'm concerned the iat2 temps are too high. the setup consists of a built motor 10:1CR, big cams, built fuel system, trans, rear etc. it ran very well with the procharger f1a setup I had previously but I recently put on a KB 2.6h with sct2600 maf, JLT RAI, accufab SBTB, 160*tstat, fluidyne heat exchanger and a ton of other stuff. anyways- for the high idle I have set the tps at 0.97V, cleaned the IAC valve, smoke tested and sprayed all potential vacuum sites with brake cleaner and nothing has changed the idle. I have also verified 12V at the iac plug. The first time I started the car with the KB I unplugged the iac and it came down to 1200 rpm. ever since, unplugging the iac changes nothing and it stays at 1700 rpm. is the iac valve ****ed? ***in an effort for idle solutions I am posting how I have everything routed on the blower: PCV port under the intake>big barb on back of blower>driver side valve cover> catch can pass side valve cover>JLT RAI boost bypass>boost gauge aeromotive FPR>port on driver back side blower manifold vacuum line out of firewall>barb on inlet closest to TB middle port on inlet>barb on JLT RAI pre TB egr blocked off my other potential issue are the iat2 temps. It's currently 39*F outside and after letting it sit at 1700rpm for a few minutes and the coolant temp coming up to 194-199 (stays consistent) the iat2 is showing at 124*F which seems pretty high to me considering the outside temp and me just reversing the car 10 feet out of the garage. The intercooler pump is working well as the coolant in the IC tank looks like a whirlpool. I pressure tested the coolant system and IC system, them vacuum filled them so air is not in the system. any thoughts here? thanks in advance [/QUOTE]
