Anybody see anything weird? Like in a previous post, I have a Check engine light, hard shift, and almost anytime I try to clear the check engine light or pull codes the truck turns off 🤔. Need to get this truck on the road any input is appreciated.
1997 f350 7.3l E4od 4x4, only mods on the truck are e-fuel, 4” downpipe, and 6637 filter kit. Guy I bought the truck from said the tranny had less than 2k on it. The truck sat for 2 years or so because the uppipes were cracked. After I swapped the motor it ran fine for about a month then he IDM went out and ever since then I’ve had this problem.
im going to try and post video, hopefully it works but if not I’ll post pictures.
My numbers at idle cold. My numbers to the floor a little warm. Ps the truck doesn’t rev higher than 2500 with a load. It is probably the slowest truck I’ve ever driven lol
What app are you using ?
ive seen this happen with scanners that are not compatible with these truck cause that and cheap Chinese obdII adapters cause this.
the e-fuel kit I installed came with a 70* spring and plunger from international for the fuel block.

The torque pro app on Android. And I have just a generic Bluetooth obd2 scanner. It seems very accurate. But then again that is the only thing I’ve used to do live diagnostics so I guess it’s possible it could be wrong.
I'm not seeing any significant boost (MAP) sensor, second small gauge on right side. Are both photos in the driveway during testing or one while driving? Did you forget to connect the MAP hose from passenger side intake to the actual MAP sensor, that would cause a slug of a truck? Just guessing at this point without additional information.

not sure if I plugged the MAP sensor in. One question I had was, what is the importance of the AIT sensor because I pulled a code for a bad AIT. Never read much on here about either sensor. I’ll search up the MAP sensor and see.
I guess what I’m really asking is does this seem like an IPR thing? I have to move the truck off the property this weekend cuz I told the guy I would. I’m going to check the map sensor if I can get by there today before dark. Is there anything I can do or check later tonight to help get us pointed in the right direction. And I should be able to answer any question you guys might have about the truck too.

and those photos are screens shots of me riding around with it. The one with the rpm’s at 670 is when I was idleing in the driveway.
Measure voltage on the connector between pin B and the battery ground looking for 4.5 - 5.5 volts. Measure voltage between pin A & pin B looking for 4.5 - 5.5 volts. If you're readings are not in spec, you need to find a short in the harness

I’ve replaced the ICP already and inspected the harness and did not find any bare spots or anything that looks worn. I will test the voltage on it hopefully this afternoon.
edit:
You are talking about the connector on the ICP sensor correct? And what test can I do to the map sensor because in my data logging the only change in that map sensor was 14.7 at idle and then never went up or down more than 14.8. I’m thinking that might be my problem the more I think about it.
