Extreme power loss, random stuttering.
I have what feels like an ignition problem.
It seems as if a coil is failing, but last time that happened it at least ran on 5 cylinders. Now it seems to go between having full power and having none at all. It will seriously just lose all it's balls and sputter, unable to rev more than a few hundred or move. I did the easiest thing today, replaced all the plugs, put some goop on them so the connections are good. Looked inside all the boots, didn't see anything strange. Thursday when this issue began I popped the hood and did the injector plug check. At that time, it seemed that cyl. 1 was the culprit. Just before this it was sounding like an ej25t, so I assumed it was a spark issue. Just now listening to it, there is a definite intermittent pop coming specifically from the odd (135) bank. This I think rules out the timing belt, which only has 14k on it anyway. When I pulled the plugs tonight I noticed there seemed to be a lot of oil on them. These are the first plugs I put into the car back in 03. They were nearing the suggested maintenance interval anyway. So I've also been losing a lot of oil lately. There is some slight leakage, I think most of it is from the odd bank valve cover... (ding, lightbulb). Here is where I lack the technical know-how to continue solving this problem. Is it possible an oil leak in the cylinders can cause this extremely rough running and popping? Is it more likely I'm losing two coils at once on the same side? Fuel pump? The way it was running when I just pulled it into the garage and let it idle, was it would turn a few normally, pop, and repeat this in a fairly regular cycle. It wasn't the same as when coil 4 had went out. It's hard to describe because it really is just all over the place. Here's the old plugs. (135246) You can see 1 is more baked than the others. The original was like this, too. 4 seems to have a bit of rust on it. That was the first coil to go. It was replaced some months ago.
