Disco II Falling Flat On Its Face
I had a lot of codes when I bought it, reset them and waited to see what comes back. Nothing has come back yet, but I have a problem. Idles fine, drives fine, it will miss one time about every half an hour, and when I am cruising it is fine, but when I hit the gas, it bogs down, like I am letting off of the gas. If I do get it to rev, it will just rev and won't really go anywhere, like I'm not hitting the gas. What should I look at first to see why it's losing power as I give it fuel? It is trying to rev, but it acts bogged down really bad. If I ease up to speed, it's fine. Thoughts?

I had a similar problem a ways back.. turns out I had a hole in the air intake tube just past the MAF. So if I stepped on the acccelerator it would actually fade to black. So maybe you should inspect the air intake as a whole. any leaks, punctures, gaps, something causing a major disruption to air flow or the consistency needed to keep your engine balanced???

Not that I can see, everything looks great on it, but I can change out that intake. Previous owner had put a K&N in it, I will recheck from the airbox back. Hopefully that will take care of it. I was blaming the fuel filter, but since it doesn't have one, that's not it. I am going to seafoam it this weekend and maybe clean out the IAC. I love the way it drives, that seems to be the biggest issue with it.

Red flag here...PO may have destroyed MAF sensor
BTW, have you replaced your front u-joints with greaseable parts?

I've got one in my pickup with 215,000 miles on it. The K&N has been in there for about 205,000 of those and has been cleaned MANY times (I used to drive in very dusty areas, which is why I got the K&N to begin with). Original MAF. Never cleaned. MANY people claim that K&Ns destroyed their MAF in the exact model pickup I'm talking about. After the first time they oiled them.

While I agree with your conclusion, I have to mention that while the oil on a K&N does not destroy MAFs (in anything), if it's coming off of the filter you did it wrong. The proof of this is that people run fine with K&N's out of the box, and things typically go sideways the first time the clean and re(over)oil them.
