Hi all,

Been away for a while. Truck has been running decently with occasional random high idle that seems to reset with an ignition off then back on, and occasional lean stumble with a VE spike at 1600rpm/40-60kpa, but more about that in a separate post.

This question is about the O2 sensor location. I'm currently running a heated 3-wire. Vehicle is my 87 R30 with a 454. Swapped over to a 7427 ECU. Stock location for the O2 is in the rear of the driver's side exhaust manifold. I would like to move it further back in my exhaust to pick up both banks of the engine, but the merge is >3' further down the pipe. Will my heated O2 be OK that far downstream?

Why am I looking to move it? I guess just being OCD and wanting to pick up all 8 cylinders vs just 1 bank.

Thanks!

Mark
