Normal Idle Speed?
[updated:LAST EDITED ON 13-Nov-02 AT 00:04 AM (EST)]I am still getting used to my new truck, but I noticed that after Ford replaced my front cover gasket (they diagnosed a coolant leak there), the idle seems a bit rough and sits about 1100 rpm. Before the service, it was smooth and under 1G.
For the F-150 5.8 in my signature, where do you all think the idle should sit at? Do you think they might have forgot to reconnect something?
Thanks for any input.

Normal Idle Speed?
Sounds like a vacuum leak. The idle speed should be 6-800 for all EFI engines. Take it back and make THEM fix it - if you mess with it yourself, it's your problem from then on.

When I brought it back to have them look at it (plus a couple of other items), they still never did anything about the idle. This all started after they replaced a front engine gasket (and I still had a leak).
While I was standing there with the service man, I asked him why they left the coolant 25% low in the rad and why there was a hose hanging off the secondary air injection system. He said that's what makes me mad and I will have them take care of it.
Does anyone know if one hose not connected to that air pump will cause the idle to be high (~1100) and not real smooth?
