Hello, I'm another noob looking for some advice.
I have a 2000 Disco2 that my wife uses as a daily driver. The other day she complained that it felt like it had a eng miss. So I took it for a drive and it has a dist miss at light load and it had a back fire though the intake (one time that I know of) she now is using my truck until I get this resolved. I have codes for Right bank lean and left bank lean and something about missed 4th gear.
The top part of the screen for my scanner has failed so I can't give # as of yet. I'll see if one of the auto part stores will loan me one of theirs. Just looking for some possible causes, or at least a direction.
Also I downloaded the rave file but can't get it to work on my comp???

 

post the code numbers, not text from scanner.

plugs and wires are a good start usually, 8mm silicone if you can get them.

RAVE links in my signature are pdf, you just open the one you want, like the workshop manual in the LT folder.

 

Also, how many miles on the engine, when was it last tuned and have you replaced the grey factory plug wires.
Always post the actual fault code number , not your idea about what they mean.

 

Hey guys, found the prob. Had 2 bad plug wires. Swapped out the wires runs great now. But while doing this I noticed a coolant leak on the drivers side head gasket. So the luck goes on. Just wondering if this eng is worth the $$$ to rebuild, or is it possible to do a eng swap???

 

Parts cost for HG kit is under $200 if you shop around.
Heads skimmed and valve job at machine shop was $250 near me.
Labor is as fast as you want to go. Shops get 12-15 hours, better DIY guys do it in two weekends with machine shop in between.

I don't fit into either of those categories.

 

Are you sure it is a head gasket and not coolant leaking from the t/body, which is very common.

 

Yep, there are places upstream that can dribble down. Valley pan also. Hope it is one of the simple ones for you.
