IAC question
Hello..i have a 99 4.6 and it is not my daily driver..i use it about once or twice a month. When i started it last night to run to home depot i could not get a constant idle...the tach would surge to about 1200 RPM and go as low as about 500. After the truck warmed up a bit it was fine and performed normally thru the 4 or 5 start cycles i did last night. After searching the site i came to the conculsion that it was most likely the IAC..no codes have been set. Just wanted to get some input from the more experienced guys and see if i am on the right path..thanks in advance.
