Could possibly be your HPOP not keeping up with demand too... It sounds like your scanner can track live data. Watch your IPR % and see how it's acting. If it's hanging out on the 70 - 80% range when you get on it and stays there for several seconds - your HPO system is leaking.

Hot idle IPR % should be in the range of 24 - 30%. 30% is probably too high. Mine sits at 21 - 22%.

 

4-5 quarts of lucas oil additive will definitely negatively affect the HPO system (injectors) and even the turbo operation

 

That's what I was thinking, but wasn't sure. Thanks for the info.

 

ok well i changed the map sensor and changed the oil and it's driving good now. last but not least it still seems to start up slow. engine temp doesnt seem to have an effect on it. any ideas?


and on a side note my buddy has a 2006 f350 and it's throwing a p0700 and the tow haul flashes when he gets in overdrive on the highway, not so much in town and driving. any ideas? lol im just keeping you guys sharp on your feet

 

hot idle ipr is at 23%

 

That's a good value.

The Lucas and recent HPO system work probably gave you quite a bit of entrained air in the oil. Lucas makes the oil foam ridiculously. You can do a search on Bob is the oilguy .com to see the results of Lucas oil additive. It make take a few medium/hard acceleration runs to get the air worked out of your HPO system. A few 40-70 medium throttle runs will take care of it. It will also help with your long/hard starts, which are caused by the air.

 

IPR % looks great. HPO system looks healthy.

Could be air in the system - give it some time on the long starts...

 

Start a new thread for your buddy, you've about worn this one out...

 

Agreed. Mark Kovalsky, our resident ford transmission engineer will usually see it and respond. The P0700 has a very vague description so I can't help you but I know Mark can.

 

ok will do on the transmission.

if i shut the truck off and start it right back up it starts up imediately but if i let it sit for 20 min or so it's a long start up. i havent put many miles on it since i fixed it so i hope yall are right about maybe air in the system. ill give it some hard pulls and see if that helps it out. once its started it shows perfect vital signs all the way through. im sorry if im wearing yall out i almost have this fixed and it wouldve been a long hard and expensive road if yall werent helping me so thanks again!

 

You can always show thanks by adding to the 'reputation' of those that help you out. Just click on the red heart on the post of that individual that was particularly helpful... I spread as much love as I can around here...

I really think you'll be OK once aired out. I was a little freaked out after I replaced my HPOP and it took several long cranks to fire after driving around town the first afternoon. Then I drove about 20 miles or so and it's started perfectly every time since.

I would also recommend getting a Scangauge or something similar to monitor your vitals. Very handy in troubleshooting HPO system and other critical systems like oil temp, tranny temp, boost, etc. About $160 from AutoZone and cheaper elsewhere like Amazon and eBay. YOu may already have that in the scanner you are using. The Scangauge can be mounted in the truck.

 

im sure youre right about the driving it and it getting better. and i will def hit the rep button for yall.

 

is there like a safe mode that the truck can go into?

dont know if it matters but i have an abs light on and the speedometer doesnt work. cant figure that one out, already changed the speed sensor

 

The 6.0 is ABS module dependant for the speedometer calibration. I'm not sure of the relationship between the VSS, ABS, and speedo beside that.
