I can't thank all the folks at this forum enough. I lost idle & power in my 2004 5.0 engine - 194 hours last weekend. Limited power underway, a double beep alarm every one minute from the SmartCraft....Not a "real" problem until I reached the dock and found I had NO idle. Reaching the dock was done by starting and restarting with shots of throttle. Now that was a professional landing. Once the engine cooled, I had a No start condition.
Anyway I'm a usual here and searched 5.0 idle issues. Like with any problem this site is a bonanza of information. Previous posts listed the alarm sequences for the SmartCraft and the corresponding alert issue. No idle and one minute double alarm could only be the IAC. While local dealers did not have them in stock, I contacted JD Neeson @ marinepartexpress.com in Maine. JD told me they alone have sold 40 this year. Arrived overnight no charge (thanks JD) and my 5.0 is ready for the weekend.
Like someone commented in a previous post - If you own a 5.0 you're fool not to carry a spare IAC & a 3/16" hex wrench. OK, I'm a believer!
* The IAC (Idle Air Control Valve) is the small solenoid behind the air filter which controls the engine idle. It has two hoses on the port side which are attached to a lower air manifold, two hex screws on top of the solenoid with gasket between the upper & lower, and one electrical connection starboard side. Took all of 5 minutes to change, but do purchase a gasket when changing. Instantly I went from no cold start to running like a champ and idled just like always.
Thanks again to everyone for all the previous IAC posts. This site is wonderful resource!!!:thumbsup::thumbsup::thumbsup::thumbsup:
