2002 7.3 injector issues?
I just replaced all 8 injectors and gaskets(didn't replace the old connections but told to only if there was a meltdown of old ones) in my 2002 f350 7.3.Idles a little rough,computer shows #S 3,5 & 8 as being bad.Replaced those 3 with new ones and computer shows the same codes?Check engine light comes on periodically,it's like a slight miss when you hit the accelerator but then runs great.What else could be the problem.Ran a compression test and it checked out and fuel pressure is 69+.My mechanic buddy is good it's just that he doesn't work on diesels much.Any help would be greatly appreciated.Brian in Central Texas.

Welcome to FTE, Brian.
Do you have the gray CPS installed? The gray CPS always shows my #3 and #8 bad, but they are working fine. How many miles have you driven the truck since you changed the injectors?

Have you had the dealer change the CPS for the recall? Look at this link for CPS info. Welcome to guzzle's CPS R&R Web Page<

Does yours idle a little rough and the check engine light come on periodically?Does it have a slight hesitation when hitting the accelerator?

What codes are you getting?
For future reference, computers can NOT determine if injectors are bad. An injector code could be anything from broken wire, loose/bad connection, solenoid, CPS etc. What are you using to interface with the PCM to run diagnostics?
Write down and then clear your codes. Start your engine, drive around for a little bit and check codes again. Post the results back here and we can help you with the next step(s).

No, no problems with mine. You should put more miles on it to make sure it's not air.
