How to check my injectors

[darrell8]

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.

what year truck is this? have you cleaned the egr valve lately

[darrell8]

Its a 2006 F350 no I have not cleaned it

[03f250stroke]

try doing that and see what happens..its free too

[darrell8]

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.
