Benny, the TTS does not control your cold idle...or any idle for that matter. All it does is work in conjunction with an injector to inject fuel direct into the intake manifold for a short period of time, dependent upon engine and sensor temperture, to richen the mixture and facilitate starting. After a few seconds the TTS become inoperative.

If your control pressures at in spec, then look to a malfunctioning AAR. It it isn't opening, or not enough, then you will see a low idle until the engine is warmed up.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
