Definitely want to hear what you think of that LPFP. Are you MPI too?

No. That was the original plan and then I decided to pinch some pennies and see how fast/reliable this set up would be.

But RS3 in the tank means if I can't get this dialed in, or if the HPFP isn't a long-term solution, we jump right to PMI.

Well your beating me to the punch with this setup. I'm wondering if this config is viable with a Mamba 3076R. I know I should get MPI to dummy proof it, but will have to save some more.

Spent some time investigating a CEL resulting from P0131 and P2237 codes that popped up out of nowhere. Haven't touched anything engine-related in months so I assume either the upstream O2 sensor or its wiring has degraded over time. Only when the car's fully warmed up, the sensor craps out and reads 0 lambda. Then every once in a while it'll read for a split second, decide it's too lean, making the engine "hiccup", and re-throw the upstream o2 code. Man, I don't wanna dish out $150 for a new sensor 😢

Can probably try cleaning the sensor but somehow I doubt that'll fix it.

Cylinder #2 misfires, day after installing New Spark Plugs and New Coil packs while idle.

Swapped 1 & 2 plugs and coils. Issues has not happened again.

The old spark plugs were good, they looked identical no oil residue or anything. I replace my spark plugs every year. When I removed my old plugs I looked down the opening and noticed cylinder #2 is dirty compared to the rest which are still clean and Silvery. since I never had misfire codes prior I decided to go along replace my plugs and coils. I took it for a test drive that same day, and did 3rd gear Pull and 4th gear pull to 6500rpm no issues. The following day I drove to work, once I got out of work i start my car to warm up and suddenly check engine light comes on? I drove home perfectly fine. And swapped 1&2 to see what happens. Today after driving to work and back, I don't have any issues?

Any ideas on what could cause residue in my cylinder? Even though I can hold power to redline no issues, is this the beginning of something more serious which might come up in the near future?
I already set up an Appointment for Compression test and leakdown test, this Wednesday.

After misfire I checked the Plugs, Left cylinder 1, Right cylinder 2
