Is the Fast Idle Valve essential ?
Hi All, I have a 79 Eldo with the 350 olds engine .The Fast idle valve has been getting steadily worse with staying open.Its getting power and I gave it a clean but it made no difference,the engine is always idling really fast.So today i thought i would see what happens if i took it out.I removed the "heater" box and spring and put the plunger straight into the opening. I now have a nice slow idle and the car no longer "leaps" when i put in gear.The only foreseeable problem i can think of will be trying to start on frosty mornings.But i would like to know if there could be any other problems with running the car without it?

Yeah, i was thinking warm up would be the only thing.Anyway , to update, tried to start up this morning.Didnt go to well, would fire up and idle for about 5 seconds and then stall.So tried giving it a bit of pedal, the engine backfired, blew the plunger out the hole, and tried to achieve warp 12.Needless to say i shut it down pretty quick, then reassembled the valve and tried again.Started up good and now strangely idles a lot slower then it did before with the valve in.
