Engine has a natural high idle...?
I picked up a 13' FR-S in July of 19' and have been driving it without any real issues for the last six months - I know the engine is roughly supposed to idle @ 650 +/-(10) RPM and the compressor/fans kick on and bring it up to 800 occasionally. Ever since my purchase, the engine has always had a steady idle of 975 +/-(10) RPM and if compressors come on, it goes to roughly 1050.
I guess my real question is what would the normal weakpoint areas be on the FA20 as far as vacuum leaks go, what I should double check besides clamps/intake tubing/torqued intake mani bolts - vehicle has 102,600 miles. Regular service history through a local dealer. It at one point stated it had an aftermarket ECU in it's Carfax Report so I'm curious to see if there's away I can tell if the ECU is flashed too, maybe causing that....?
