2013 Redline...Rough idle...missing and ESP.

My money is on fuel pump...

Needless to say is running lean due to crapped out fuel pump. This has happened to me twice, don’t put under load or enter power enrichment, putter about in closed loop.
Next step is to log / monitor the fuel rail pressure, look into doing that with your device. Should be near enough to 400 kPa (58 psi). If drops to around 250 then yeah need to open a hole under the back seat with a cam opener, take out fuel pump basket and stuff, replace the pump, fabricate a cover over the new porthole and sweet.
That is easiest and cheapest, otherwise it is sort of inaccessible.
EDIT: beat to the punch, same advice.

I just connected the scan tool to check fuel pressure....at idle and 2000rpm I have 57 - 58psi.
I will take it for a drive shortly and monitor fuel pressure.
Thanks for the help.

I meant log the fuel rail pressure when the fault occurs, will not show low pressure under idle or low load.
Drive around for a bit get the pump hot, note fuel level on dash and fuel pressure when you stab it.
Check fuel pressure in this video top left, is ok to drop a bit with really high demand but not idle and under 2000:

That’s why you need to log the fuel pressure data before and during the misfire event. Ultimately it is the lambda ratio going lean when ECU commands stoich or rich that’s the issue. In video above, lambda bottom right stays flat, as commanded. I suspect yours does not, and I think is coz pump. Log will tell.

What are your long term fuel trims at?

So I took her for a drive and I had my son keep an eye on the scan tool, advised him to let me know if it dropped below 55psi.
Stayed between 56 and 59psi for the whole drive, I planted it a few times and it never dropped below 55psi.
Checked for codes again and had.
P0171...P0174...P306...P018B.

I wouldn't know.
Do you know if a basic scan tool would give me that info?
I know I am asking a lot of questions about all this, steep learning curve for an old biker..LOL

Should do under Data display

Well that’s actually good news, now to check spark.

Well that’s actually good news, now to check spark.

It is good news ey, when I finish my late lunch I will start testing coils with meter.
Will set MM to 200ohm for primary and expect 0.3 to 1.5.
And set to 200K for secondary and expect 5.0 to 7.00.
Above setting ok...used it for old cars and my Harleys.

I will check now..cheers.
