6.0 has a cold

My 03 F-350 6.0 powerstroke has 98,000 miles. When I first crank it up, it won’t hardly pull out of the yard. After it warms up,it runs fine. I have replaced all injectors, fuel pump, IPR valve, & IPC sensor. Also on cold startup the engine used to idle up until it gets warm, but it no longer does that. Could there be another bad sensor?

Diesel Pick-up? Are there any trouble codes? If there are codes, you can go to autozone.com, register, return here, and click on this link to suggestions of what to check for each trouble code: http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?partName=Diagnostics&pageId=0900c152801df16e&partId=0900c152801df16e0c152801df16e

The only trouble code is a P132b and I have not been able to find out what it means as yet. I cleared the code, but it didn’t change the way it runs before or after. I went to autozone.com, and they did not have the code listed either.

This may help. I typed ‘Ford DTC P132b’ in the Google search engine, and found this at http://www.ford-trucks.com/forums/760607-dtc-help.html.

P132B (F-Super Duty/Excursion Early Build Only)
Turbocharger over/underboost condition
MAP sensor, VGT actuator, intake and exhaust leaks

And this

Well since you were in late last year, everything should be pretty well up to date on your truck. You do not mention if you truck is having any running problems or not, but TSB 06-24-6 sorta stands out…

6.0L - BUILT ON OR BEFORE 9/29/2003 - DTCS P006A OR P132B - LACKS POWER, SURGE, OR FLUTTER AFTER FIELD SERVICE ACTION 06E17

I have not taken my truck to the Ford dealership for repairs. Are there any computer updates that are only available at the dealership? Thanks so much for your help.
