It's not misfiring, you just have "variable displacement" lol.

Oh man, that's still going on? Any new ideas as to where the misfire is coming from?

Hang in there, we've all been stumped by seemingly unsolvable problems. Good luck getting it running right.

[]Wilson Oberholzer

Sounds like it's time for an engine swap. Why bother fighting with an engine that doesn't want to work, especially when it's not even a very good one?

[]Joost Van Dien

Check everything carefully! Look into the cilinders for water/ oil. Check all cables and wires.

I hear you there! Don’t lose hope tho. Just keep pressing on!

[]Robert Sixto

Time for a break, take a week away from it, drink a glass of your whiskey/bourbon/scotch of choice, and revisit it with a calmer mind. You'll get it going, now it's just a matter of deciding the best way forward. 👍

[]Craig Crall

Jake I haven't followed your posts, but I remember that you were having issues with the LT4. I take it , that you did a compression test as well. How much lower is cyl 3? Could the valves possibly be miss-adjusted?

That picture/chart is an absolute must have for anyone who wrenches on their own (or others') vehicles. I have it posted as a sticky on an ECU tuning forum that I moderate. I have no idea why I don't have it saved on my phone

[]Jake Johnson

My thoughts exactly. Sensors can tell you a lot, but there's no true replacement for being able to look at the physical evidence of what your engine is doing.

[]Wilson Oberholzer

Sensors can tell you what's happening before air goes into the combustion chamber and after it comes out but they just won't tell you what's going on inside. I don't think they make a sensor that tells you if your valve stem seals are leaking either, lol.

[]Wilson Oberholzer

Have you changed the fuel filter since you got back on the car? It might be worth checking out and seeing if sediment/rust deposits are getting into your fuel system. I know when my S-10 sat for a few years with only a partial tank of fuel the tank rusted really badly and I went through a fuel filter every 2 weeks. Checking it would give you an idea without having to get the fuel tank out.

[]Jake Johnson

Changed the fuel filter a couple of weeks ago. Fuel pumps are easy to get to on my car.
