Engine races on startup
- Thread starter XJ16FW
- Start date
I found this in another thread, it might cause the racing at startup, especially if warm/hot.

Re: Idle RPM's unsteady, too low, then too high
--------------------------------------------------------------------------------
Four things here - TPS, is it good and is it adjusted properly? IAC, is the area clean inside the TB (throttle body)? If your idle speed is changing the IAC is probably working but they do stick open sometimes and cause very high idle speed upon warm/HOT restart. 02, Renix will idle erratic with a bad and/or weak 02. Finally, vacuum leaks - intake manifold bolts, perhaps the MAP vac tube is ruptured?
Get the FSM download and study things. It's not that complicated but a few things need to be handled in the correct order with regard to TPS adjustment.
