The fuel rail sensor is technically what started all my issues. I may try to get ahold of an original part number sensor. JT sorry but the ones you had given me were in the bag in my garage when it got destroyed unfortunately. I'll try to get ahold of another one to see if it makes a difference.

What would cause the sensor issue you think? The sensor itself or the wiring? I'll check the ITFP for sure.

I used to think that but then I realized that from what I could tell a lot of vehicles operate between the 20-60 or 70 psi range. Any higher and they leak and blow seals etc.

I think for this reason alone I am going to pull the itfp and check it out and then go from there. I run 10w30 and it sits around 20psi at idle and normal driving it is around 40psi and then obviously increases up into the rpms. Would you think that the stock fpr could cause this in any way? It...

First off wow you seem to be full of diagnosis knowledge so thanks lol Secondly, that's what we were trying to do with the voltage. So using desired vs actual hpfp pressures could possibly be used or that isn't enough?

The blip in valve advance could be happening when the motor bogs down as well to keep it from dying idk. A lot can happen when an engine is dipping as fast as mine while this odd thing is happening. Tuning has shown typical intake valve advancement from what I understand so I feel like it could...

I appreciate you bringing this up. I really hope this isn't a mechanical issue. I swear I have done the timing on that thing 3 times and this time has went much better but that would be very frustrating. Electrical problems are super frustrating too though but still lol

Here are the latest logs I have taken. The driving log will probably be the most obvious but also the idle logs I am sure too.

Me and JT thought maybe the signal was being dropped or something during those dips which would maybe point to the sensor instead of fueling the way I understand it. I'll post the logs.

I'll pull the itfp and then see if maybe the sock is stopped up or something. Anything else to check while I'm in there? The datalogs I have weren't recording hpfp voltage and only actual pressure so I am going to try and get some new logs this evening of it doing it but with the voltage logged...

@Enki @Rokusek @phate @JohnnyTightlips @Easter Bunny @Matt@DamondMotorsports Calling for some help on this situation as I am still experiencing it. Car stumbles hard after being driven for 20-30 minutes and is fully warmed up a while. Hpfp pressures seem to randomly drop to 500 from 1500...

My rear subframe definitely needs pulled and gone though and coated. it will need a definite sand blasting first lol It's so rough and makes me sad.

Big difference on those wheels for sure. That still fits in the stock ko4 housing? I bet that's a massive difference! As for unemployment we get that but it depends on your circumstances how much you get paid. I am a pipefitter and don't get laid off work much but about every 5-10 years there...

Definitely perks to having the government pay your medical stuff lol

Sorry to hear about everything and sorry that place is so strict man. Gotta be rough. I am thankful for our freedoms here for sure.

Indiana is no inspection just registration for plates that's it. Love it here too lol Cops don't care what you've done to your stuff at all here at all

Glad to see your build starting to come along and pay off!

Glad you chose to join in lol I also have a speed 6 and it is fully built. If you have any questions feel free to ask me! Donate a little to be a metal member it's not much and then you can pm ppl :D

I try to stick with the "keep it simple, stupid" type thinking and try not to overcomplicate stuff haha

Oh ok gotcha. Yeah sounds expensive for sure. The more complex stuff is usually means the more often it has to be fixed lol
