IPR problem maybe??
Alright was driving to the house earlier today. normal speed, no hot ******* blah blah. Truck just started feeling out of the ordinary when i would let off of the gas. it seems that it revs a little faster than normal also when i accelerate in gear. pulled the codes and i got:
- P0470 - Exhaust back pressure sensor, have changed this twice and clean the tube out regularly. always pull the code for some reason.
- P1209 - ICP system fault, first time getting this
- P1211 - ICP pressure above/below desired, first on this also
- P1247 - Turbo Boost low pressure, first on this also
So, from what i can gather from the P1209 and P1211 is that the IPR valve failed maybe??
But really i am concerned about the P1247 and have no clue why this would be coming up.
Any help would be appreciated thanks in advance

Well went for a drive, put the edge in level 4. Floored it around a bit to see if anything would happen. Was accelerating hard on the interstate and I just cut out for a couple seconds. It felt like when you hit the govoner of a vehicle and it cuts out... Anything?

OK, finally got some time to mess with the truck. Yes the tin nut is still on the IPR and it is tight. so i guess i am now wondering if i should buy one of those rebuild kits or an actual sensor. Any thoughts?
Also have another issue with EGT's. Got a low pressure turbo DTC code the other day. Ever since then anytime i give the truck more than 1/4 throttle my EGT's hit upwards of 1800 and 1900. I have the Edge attitude w/ juice. I have run it in every setting including stock and the problem replicates in every setting. I can run the truck around fine as long as i don't mash on the gas. Any ideas?? I have asked a couple people and a "boost" line under the passenger battery has been mentioned to me by multiple people.

Oh. Just wondering. Last time I saw a P1247 it was due to a dirty fuel filter.
Your symptoms sound a bit like a fuel supply issue. You might try connecting a fuel pressure gauge to verify the flow is adequate.

i used an oem sensor. I checked the fuel pressure at the bowl and it is within spec. Well i guess ill just change the IPR and see what happens, since that has not been changed yet. Can't hurt i guess.
