lean bank 2

So ive been running pretty lean to say the least. I misfire when stopped at lights or just stopped in general. I do have some acceleration loss of course. My computer also won’t throw a code although I know i’m running lean because of the live data on my scanner. I bought a smoke test machine...

Hello, Recently my 2000 xlt with the 4.0 SOHC has been stalling when idling. It will start fine, drives seemingly fine for the most part (maybe a little sluggish when accelerating). But whenever I just park it and leave it to idle for more than 10 minutes or so it will stall itself out. It...

So now I’ve tracked the source of the vacuum leak so I thought. I have AC now and I’m running a lot smoother but now I’m lean on bank 2 still but only when the ac is off. So when you the AC is off my oxygen sensors are reading fine but I’m lean on bank 2. When my AC is on my oxygen sensors go...

I’ve had this lean code for awhile now. I’ve narrowed it down to what appears to be a vacuum leak but I want to share my trucks numbers just to confirm. I also want to share some weird stuff that’s been happening. So my long term bank 2 has been in the 20’s for awhile I’m assuming this is my...

Hi there! My 4.0L SOHC engine has been running quite poor in the morning lately. While I realize that when it's very cold outside the engine will take longer to start, I did not expect it to be extraordinarily loud (consistently greater than 95 dB on my phone's microphone) and very rough...
