Hello, I hope everyone had a great year so far. For past couple weeks I have been trying to get rid of a SES light. At first it was just a P1093 which would pop up intermittently. Basically disappear after couple drive cycles then come back after about 25 miles. I am gonna give a full timeline of what I have done so far.

I first tried to clean the ICV since it needed it and at the same time replaced the lower intake boot. Before installed the ICV again, I did shake it to make sure it moved and well it seemed ok. 25 miles later SES popped up again. Still was p1093.

Next, I checked my MAF using OBDFusion. Fully warm at Idle it was reading 2.6-2.7 g/s. Which is pretty low. I bought a VDO MAF and It came in a continental box. I know that continental owns VDO/VDO is part of continental so I was sure it was OEM. Installed it and MAF was still reading 2.6-2.7 g/s. Drove for 25 miles and SES is back. I decided to return the MAF since the old one seems working and Ive heard mafs last pretty long even past 200k.

Next, I swapped my pre-cat sensors. Bank 1->2 2->1. They are about 25k miles old so they shouldn't be a problem. but still Maybe the pre cat bank 2 sensor was reading wrong. I was hoping it would switch to Bank 1, but now I have p0174. I made sure the o2 sensors were tight, maybe I installed them wrong? I retorqued them and still have p0174 and p1093.

Fuel trim wise, according to OBDFusion, STFT B1 was 2.34%, LTFT B1 was 2.34%. STFT B2 was 25%, LTFT B2 was 1.56% based off my last freeze frame. Engine was at operating temps for this freeze frame.

Today, I pulled in INPA and wanted to monitor fuel trims while going for a quick drive. At idle Bank 1(Lambdaintegrator 1) was sitting at about 0.73 while Bank 2 (Lambdaintegrator 1) was sitting at a static 20.86. While cruising both were -0.50 to 4.84. It seems like the lean problem is only at idle. My latest idea would be that my ICV is bad and while idle its stuck or the computer cant move it.

I would like to point out that my CCV seems like its fine. I did the only cap test and don't have black smoke from the exhaust.

My latest codes from PASoft were
Oxygen Sensor Controller Bank 2 deviation too great deviation rich(lean) this would be p0174.

Misfire Cylinder 4-5-6 misfiring during warm up, worsening emissions

Trimming, oxygen sensor before cat , bank 2, too great in rich range. this would be the p1093

I am currently loss and would like some input. Thank you!

Edit: Got rid of the colors from the codes. The colors were if it was present or now.

P0174 FIXED:New oil cap, brake booster vacuum line was loose and lower intake boot needed to be tightened.
