I recently had a bad miss in my 02 Forester 2.5. I first thought maybe a fuel filter or water. I replaced fuel filter, air filter, plugs and a couple bottles of dry gas. Check engine light went out and ran fine for 2 days about 500 miles. Now it acts the same won`t pick up under load for a few seconds then takes off. It only does this occasionally and acts like possible fuel problem. Also no check engine light on. 1 sensor on throttle body adjusts idle and another round shaped sensor in front. Help??
Also, if you got some bad gas containing water, it may take more then 2 cans of dry gas. Suggesting adding some more, one can per tank full for two or three tanks of gas.
After posting yesterday the car ran excellant and engine light came back on. The mis is more evident at low speed and I don`t have acess to a code reader. I`ll try the wires and more dry gas. The car has around 166,000 and I guess wires may be breaking down when warm, doesn`t miss when engine is cold.

When replacing the ignition wires be sure clean the socket where the wire plugs into to ignition coil. Often times I have read on Suby news groups that corrosion at this connection will cause intermittent miss firing. Do use OEM wires if you can as they are top-grade at a reasonable price. Ed
Back again. After all this time and lots of money, it`s the converter. Any Idea of how to clean out the converters on this Forester? It comes off the Y pipe to the 1st converter then a section of pipe and the 2nd one. This is a 2002 with 172,000 K and can`t find a used one. Subaru says 800 for a new 1. There are no emission tests in my state so I can work with the old one .

Well, if you were in Oregon, I would say the reason you can't find a used convertor is as I was told, not legal to sell used ones. However, I have had a convertor rebuilt before which was not a penny cheaper than just ordering one. Can't really say for other states, but this was before Oregon and several of the northwest region here adopted the California emissions regulations, so it may just be the same way in other states now too.
If it were me, I would take the convertors off, dump out any debris to see what comes out. My convertors were both broken into pieces by the time I had them redone, and the theory is, the clogged convertors caused too much backpressure in the poor little motor, and although I never did post mortem, a cylinder lost all but 15lbs of pressure maybe due to a burnt valve. Could be either way though, the valve could have burnt, causing the convertors to run too hot, thus failing, but whatever happened, it was neither nice, nor cheap.
Otherwise, I dunno if it's possible to clean convertors that are otherwise intact. I know some folks just kinda, hammer them out and then dispose of the broken bits in the trash then reinstall the hollowed out exhaust piping back. Sucks for the environment though, so I would rather that not happen. Anybody know if the loss in backpressure from doing this affects the motor adversely?
I've rodded out plugged converters with a length of rerod and dumped out the spoils. The length of pipe and resulting friction on the inside walls of the pipe ( "C" value in engineering terms ) seems to maintain adequate backpressure that there is no detriment to engine performance. Your minimal negative contribution to the environment is like a fart in the wind when compared to the contribution that the Bush's administration has allowed his industry cronies.
I agree about the global warming, which seems more fad than science, but I really have no basis to say anything about the long term sustainability of releasing unhealthy things from our cars into the atmosphere.
Try telling Siberians you would like the weather to cool off a tad. (-;
We're just on this planet for the ride. It's a lot bigger, stronger, and more complex than we realize. I'm not sure that volcanoes, lightning-initiated forest blazes and other natural occurances can be fitted with a catalytic converter.
That said, nothing wrong with burning fuel cleaner and more efficiently within reason and having the freedom to choose to do just that.
If you haven't gotten the memo recently, anyone still thinking like this now that nearly the entire scientific community is in agreement on global warming is making like an ostrich and choosing to be an uninformed idiot.
"Let Al Gore deal with it" is an equally assinine way to think about this too. That's just laziness. The title of his film really says it all "An Inconvenient Truth." The truth of the situation is no longer subject to debate. Hell, just a few days ago we saw this happen:

If serious steps aren't taken, serious shit can and will keep happening to the planet. It's not Chicken Little rantings anymore.
To the OP, please consider getting the catalytic converter fixed even if the state isn't holding licensure against you. Should the state have to mandate doing the right thing to people?
Hell, personally I feel bad about having a car that has all emission systems in working order, yet only gets 25mpg on average when I don't need AWD 9 months out of the year.

Maybe the planet isn't built for some of the pressures advancing humans are putting on it? The planet will survive, but can we?
I'm all for advancement, and don't think we should be walking everywhere. However, I also think we should be a lot more respectful of our environment with some very simple, easy to implement, common sense changes.
As I drive through my 'hood on garbage day, I'm still blown away by how many people don't recycle at all, how much trash a family can generate, and that four mothers who live next door to each other will ALL individually drive less than a mile to pick up four individual kids from school, in four vehicles that could easily transport all four kids, and leave them idling side by side as they wait for the kids.
I just think we all need to use a bit more common sense.
Yes, but what truly do the scientists who "know", know? How much of the planet's oxygen really comes from the rain forests in the Amazon we're told to protect "or else"! How many millions of years do scientists tell you it takes for mountains to form, yet, look at the semi-recent activity on Mt. St. Helens in Washington state. How old is this ball of mass we find ourselves floating around the sun on - somehow the exact number of years escapes me, as nobody scientific can seem to form a solid number yet. While if only to myself it may "seem" that global warming is more fad than science, that's merely my own opinion. For what it's worth, I don't remember there to being any more than theories concerning global warming, making them conjecture, the opinions of some in a scientific community. But before you think me boorish, I also prefer that folks be good custodians of the environment around them, but it isn't up to me to enforce such things as these. Err on the safe side and take care of things you don't know the outcome your influence will have, but all within reason. (-;
Why are catalytic convertors so expensive? Is it the platinum in them? If it were a manufacturing thing, seems cost could reduce in some way proportionate to demand, shouldn't it? Why can't used convertors go through a test and be recertified for so many more miles? Somehow I don't think this is all about the environment.

You seem to share a common misunderstanding of what a scientific theory is. It is not just a guess or speculation but rather a self consistent explanation of the mechanisms behind observable events or facts. It has predictive value and is capable of being tested or falsified through observation.
