a couple of issues after motor swap.

dentexpowerstroke · Jan 7, 2013

Got my motor swap done, along with studs and springs. Now it feels extremely low on power, won't build over 27psi of boost. It also has a tea kettle sound to it which has me nervous being that it was studded one by one. Also when I get on it hard and let off it will stall itself out, I figure this is ipr related. Haven't got a chance to check it on a scanner or leak check the boots and everything. Just wanting to get some opinions on something I may have easily over looked.

Sounds like lots and lots of air.

Boost leak, turbo not seated on mount?

Dying sounds like ICP sensor or IPR.

dentexpowerstroke · Jan 8, 2013

Need to check turbo mount tonight. It's something big enough for close to a 20psi loss. i figured the dying was ipr.

Check up pipes, you have full egr delete?

dentexpowerstroke · Jan 8, 2013

7.3, can't find soot anywhere. turbo mount bolts were all tight. Tomorrow ill build a boost leak detector. Checked all the boots, they all visually look good. I'm thinking it may be a plenum leak but 20psi seems like it would be something obviously leaking.

Stupid me!! Check map hose, map sensor, you got ebpv deleted?

dentexpowerstroke · Jan 8, 2013

Yeah t4 with a 366 so all that stuff is gone. Map hose looked good, it'll be scanned Saturday so ill check out map and also ipr/icp to see what they are doing.

Let us know bud

I wish you guys were closer, I'd bring it to you. I'm tired of this thing already haha. Fuel pump decided to crap out on the test drive when i first got the swap done, now its one thing after another.

dentexpowerstroke · Jan 12, 2013

I got around to checking everything today. Found one boost leak, fixed it and rechecked everything. It runs good, still feels low on power compared to what it was. I can only see 30psi tops, checked for boost leaks and exhaust leaks and found absolutely nothing after the first leak was fixed. Didn't get to scan it will do that tomorrow, any more ideas?

I just don't see that much fuel being pulled from the tune to only see 30psi, tho it won't go above 1200* at wot.

dentexpowerstroke · Jan 12, 2013

Pulled codes, all I got was 1294 injector high side open bank 2. Don't know what that means.

dentexpowerstroke · Jan 13, 2013

Forgot to mention the drive valve cover came unplugged the other day so the 1294 may be from that, it came up when i did the koeo test.

dentexpowerstroke · Jan 16, 2013

got a chance to drive it and scan it. Has started to stall out more and more now.

wot icp was 3150 and ipr was ~70%
when it was stalling at a stop sign icp was 900 and ipr was 30-40%
running fine at a stop sign icp was 550-600 and ipr was 14%
at idle after driving icp was ~550-580 ipr was 22%
cruising 30-35mph icp was 1000 ipr was 30%
ran a cct test got p0266 code- cylinder 2 balance fault and a p1294- high side open bank 2 (accidently started it with the valve cover gasket undone the other day, don't know if this caused it.)

I have a new ipr on the way, icp is ~3-4 months old. I don't know exactly what I'm looking at with these numbers any help would be apprectiated.

02BigD · Jan 16, 2013

Way too much IPR. What kind of HPOP are you running? Hybrid injectors?

dentexpowerstroke · Jan 16, 2013

stock hpop on 250s. The whole thing is the week before the motor swap it was holding icp and ipr fine, that's why I would find it hard to believe that the hpop has gone bad in between the time I took it off one motor and walked over and bolted it to the new one. My new ipr will be here today so I'll test that out. It's getting a t500 here in the next few weeks too.

02BigD · Jan 16, 2013

Been thinking about this for a bit. Do you know the history of the motor you installed? I'd be very curious what kind of psi the lpop was putting out. Could be starving the HPOP?

dentexpowerstroke · Jan 17, 2013

No history on the motor, I thought about that today, I was thinking the ipr may have been stuck open and just bleeding off even tho the computer is trying to tell it otherwise. I'll check out lpo tomorrow. I just know the motor had 180k and came from a wrecked truck. the only thing we really changed off my old motor was pull the ipr and clean it, thats why i figured that. I'll post back up after the new ipr and lpo check.
