Starting issues with 03 EXPY 5.4 EB
I had a few things change by my local dealer last week,plugs,t-stat,inlet manifold and coil. Since this work was done,the truck is messing around.

(1) The heater vents stop blowing,but warm air is present. I took it back,apparently they did not connect a hose.

(2) My wife was having difficulty starting the truck,when I went to look at it,I eventually got it started,but i noticed that the temperature gauge was not reading. I drove for an hour and still no response.

(3) I also notice the truck is idling at about 1100RPM.

Any opinion on this matter is welcome

Will take the truck back to the dealer in the morning.

Thanks
