02 cold exhaust

[badcomp1979]

I have a few questions about a 02 7.3 that i have,i'm curios if any one out there has ever had this issue,at start up the driver side exhaust is cold and passenger side is hot,wandering if hpop is bad?

My first thought would be the Under Valve Cover Harness (UVCH) plug that is prone to unplugging. Good news is, the drivers side is the easy side to check!

i might not have listed my thread correctly ,the driver side exhaust is always hot on number 8 and cold on 2,4,6 until you get it hot or drive it then they all get hot which it was already doing before i changed out 2,4,6 injectors for new ones , which were only 3 months old ,and when i put them in all good until week later let sit over night and now at start up pipe cold again and no power for awhile.anyone ever had this issue before ?

Does any one have this problem with there 7.3,or have had this problem in the past?

Time for a buzz test when cold!!

So you think those injectors could be stuck closed cold,I went ahead and changed out all 3 that didn't have oil coming out about 4 weeks ago because it was hard to start and when i did it cranked right up with oil coming out of all of them then about a week later and only after sitting over night cold exhaust again,its funny that those 3 are doing the exact same thing, the truck runs really good after you go 3 miles but before that barely moves then comes alive ,but at least it starts.

get ahold of an ae unit and run buzz, contribution tests, etc.

so only do test when its cold right?

i checked all 8 when it was in bad shape but when it was hot they all checked out good.
