Re: Bad o2 make the car earthquake shake?

Thank you for the input everyone... I'll have some free time this morning to mess around with my a little bit but most likely I'm betting I'll be sending off a few 20s for some O2 sensors and take it from there.

I did notice when I took off the H6 cover (don't laugh at me ) one of the lines on the passenger side seemed to be loose or close to coming off with some sort of fluid showing some sort of previous leaking around the area.... I of course tightened it back up in hopes that may have had something to do with fixing it.... but alas, no go.

Re: Bad o2 make the car earthquake shake?

Finally.... my eBay o2 sensors have arrived minty fresh. I'm pretty excited about getting them in sometime soon this weekend with hopes it will resolve my problem. (I'm having withdrawals)

Wish me luck, I'll be doing it on my own!

Bless your heart!
We sure do wish you luck, but we should go a step farther and pray for a miracle. I will be the doubting Thomas

Please let us all know so we can rejoice with you!!!

Re: Bad o2 make the car earthquake shake?

So the F word is at the tip of my tongue and I don't mean frustrated either...

EGR valve is fine, I had someone take a look at it and said it's fine and there is plenty of pressure or whatnot.

I got the o2 sensors in... replaced them both.. (which the one on the right side needed severely). Start it up and it's still running the same.... took it to a local shop and he wanted to hear it... said it sounds like it's missing out... misfire, asked when it had a tune up and I said it's hard telling as I've only had it a few months. He quoted me $125 to do the spark plugs. Got the plugs and had a friend help me do them, which totaled in about $55 for parts and a nice dinner for my friend .

Anyways, that didn't appear to fix it, either. I guess between 3 people, everyone has said it's most likely the coil pack.. or one of them rather. One of my buddies is going to run a multimeter on the coil packs to test them that way and while removing the spark plugs the other day, the one in the back, closest to the passenger side seemed really dark... the rest of the spark plugs were fine.... or normal used color.

65 miles later with new plugs and o2 sensors... with no check engine light and still running like crap. I figured if one of the coil packs were bad it'd throw a code but everyone else says that's not true.

Any ideas? Anyone have any decent working coil packs they want to sell me? or should I just buy new?
The last thing I want to do is go into a shop and feel like a tool because everyone says "OHhhh, it's a Subaru!" = MONEY, in their eyes... because their such a disaster to work on. I'm really sick of the way shops are or act just based on that fact.

Re: Bad o2 make the car earthquake shake?

Some day some one will work out what is going on with the 02 code that is not the 02 at all.
It has to happen.
I am one of the many that are there disparately looking for it to happen. I would replace my engine in a heart beat if I thought it would cure my problem but I don't think there is a chance that it would.

Re: Bad o2 make the car earthquake shake?

So apparenlty he can't check the packs with a multimeter but tested the wires that connect that run back to the cars computer, I believe? Testing those on the right side of the engine (passenger side of the car) came back with:

(at 2000k)

rear = 1000
middle = 1570ish
front = 1629ish

Does it sound like the rear cable to the computer (or wherever it's going) needs replaced? 500-600 seems like a bit of a drop but I don't know anything above what it's reading in regards to the electronics and such.... apprently neither does my friend.

Is there a way to test the coil packs with a multimeter and if so at what setting?

Re: Bad o2 make the car earthquake shake?

you can test them where they plug onto the wiring harness by the throttle body.

Well, my buddy is gone for the night and took his meter job with him. I did some more searching and apparently I could remove fuel injector cables one at a time until I find out which one doesn't make a difference to determine the issue or which coil pack is bad... (if that's what it really is).

I had someone else look under the hood today... his first words out of his mouth was:
"What the hell is that?!" in regards to the engine......

hmmph

Re: Bad o2 make the car earthquake shake?

still not a coil pack!
Sometimes these things remind me of a dog chasing it's tail

Would be nice if it was as simple as a coil pack

I hope it's just a coil pack..... pinpointing the problem would make things so much easier. (subjective to the known problem at hand, of course)

Re: Bad o2 make the car earthquake shake?

did you find out which cylinders where not operating?

Im wondering if you have a bad cam sensor, the way you described the super rumbling if half of your cylinders are missing.

I'm going to hopefully find that out tomorrow by doing the fuel injector cable pull trick. One by one starting with the one I think is bad.

With that said, it is running a'bit better after the replacement of the o2 sensors and the new plugs but it's still not right (rough) and pretty much maxes out between 45-55mph before it starts shaking out of control.

Tom, There is something on the EGR valve that can be moved while the car is running? Should the valve be open or closed? How would I know? Where would you touch the thing? Doesn't it have a couple of exhaust lines coming to it. Could that be a little toasty for the fingers? I need to work this out on my car or something

one other thing to check. look at your crank pulley and the plastic cover behind it. sometimes it seperates and rubs into the plastic causing it to break the plastic off in chunks flopping around behind your timing belt cover causing a the belt to jump. while your cars running flip the throttle while your under the hood and watch the pulley for lateral movement.
