Before anything else I'd pull of the secondary convertor pipes and get a look at the primaries to check if either one has broken up.
Well checked compression. Cylinder 6 is at 90psi. Threw some oil in there and came all the way up to 190. So you may be correct and now my rings are shot. 130k miles.
Sheís been really good to me since 2010. Mostly minor issues.
But looks like Iím either doing a rebuild or a swap. Not sure whatís the best option here, will have to do some research.
Down to one vehicle now, good thing itís almost tax season because I wanted to get a daily driver anyway.[/QUOTE]
Yeah I think you've mostly confirmed it with the compression test, at this point you could pull the cat just to completely confirm it but I think it's safe to say it's probably broken up. @jsexton
had that same thing happen to his X and he ended up swapping the engine I think.[/QUOTE]
I am having a lot of people tell me it could be the computer at fault. I believe, but could be wrong, that I have had low compression in that cylinder for a while. This would explain the rich exhaust smell and 11-12mpg that I have had for a while. I don't think low compression in one cylinder would cause a random multiple misfire code. I haven't touched the vehicle since I discovered the low compression. Just been sitting now while I save up money and decide what to do. If anyone has suggestions as what else to try before I do a new engine/rebuild the current one I am open to anything. I know it still needs it but I dont want to do all that work and it still be something else because then I will just want to burn the damn thing down.
