I have a 2000 7.3 and it runs sluggish until it gets warm and then it's like a light switch smooths out and runs great. Any ideas what to look for?

 

Injectors. ..

 

Need to pull and clean or service or replace?

 

Yeah, injectors. How many miles on them? I had the same thing going on, replaced them all.

 

285k never turned a bolt on truck...lol, Also have oil in valley of intake and looks to be running down backside of bellhousing. Truck has only had 1 oil leak since ive owned it and that was on drivers side oil pan area a round tube in the cold winter time would chunk out a little oil. Still need to fix that also

 

You can give your injectors a more life if you shim them. I used this kit and comes with everything to shim them including tools.

308K mils on mine, and it's been doing the same thing for 60K-75K miles. I have the shim kit, but haven't found my ROUNDTUIT yet. I just let it idle until all the injectors are firing (only an extra 1-5 minutes for where I live (it's an ambient temperature thing).

 

Could be stiction and “possible” some of the oil additives could buy you some time. May be worth a shot. May not work but won’t hurt anything. Have definitely worked for some.
I’d look into those oil leaks though. check hpop lines. They are likely in need.
