How to check my injectors

How do you tell if you have a injector going bad or is bad? Will the truck throw a code and will the CEL come on if so? Thanks for you help

you would need to do a contribution test or/and a buzz test. that will check the electrical end of it and the contribution will check its flow. you need to have it hooked to a scan tool. snap on, ford dealer scan tool.

typically though if you were having a bad injector/s you would be getting a hard start, rough start, miss, smoke, things that would lead you to believe the truck isnt running normal

I am having a hard start it seems to crank for so long before it starts and when it does it runs rough for a few seconds then smooths out. After the truck has been ran though and you go back to start it later it starts fine just when it has set over night.

I have never taken the egr valve out I know where it is and know there is two bolts that hold it in but have heard they are a bear to get out any tips on how to do it? I don't want to break anything.

you may also need the computer recalibration. Redoes a few things to help with cold start issues. There is a TSB on it.
