I believe I have the dreaded IAC Idle Air Control valve problem on my 03 5.0 MPI Alpha. It will not stay running at idle, dies immediately after it fires. If I advance the throttle some it will start and run but then die immediately when I return the throttle to shift gears.
Just prior to this happening I was cruising along, engine running fine, and then all of a sudden I get the warning tone.....two beeps every 60 seconds. This lasted for several minutes until I came back to the ramp, then when pulling the throttle to enter a no wake zone the engine died. It would only run with the throttle advanced, I was unable to get it into gear as it died immediately at idle. From what I have read on the Internet this is a very common problem on the 5.0 MPI. Anyone experienced this?? Are there other weak areas on this engine I need to know about......spare parts to carry etc????
