High Idle 2 ... (& random A/C question)
Got a question for you 3.9 v8 lovers...
Every time I start my engine I'm getting a high idle, around 2,000, sometimes slightly higher. I don't run the A/C (next question) and I have new spark plugs, and run Amsoil everywhere. When the truck is warmed up, the idle is perfect. The IACV is clean... The local mechanic (a Jag/BMW/sometimes LR private shop... they suck) can't fix it. It took them 3 times to set the timing.
Any ideas? The initial idle stays high for sometimes a minute, it's getting out of hand.
My 2nd question has to do with A/C. I purchased a brand new A/C unit sometime in 2003/4... never freakin' use it. My wife and I do a lot of kayaking and I need it to work. There's a plug that goes into the engine to measure the temp to allow the A/C compressor to turn on. I have the original parts manual for this, that I actually took each page and put it in plastic... Well, my dumb ass took it out of the binder and now I don't know what that part is called OR the part #. It's a round plug, with 2 metal conductor pieces sticking out.
