Yes, everytime I goto a yard I'm right at the brink of tears cause 99.9% of the roos I see have been hit beyond repair..........snif..........poor little roos. OK, maybe I get just a little too attatched to a Subaru.

No probelm. Glad to help out fellow Suby owners!

I'm gonna try putting a new o2 sensor either just past the cat or right at the end of it. THat way I can at least re-connect my A/F guage and see where she's running.

Yeah, I did adjust the TPS according to the FSM cause she wouldn't drop below 1500 RPM. Now she idles at the proper RPM, but I have that dead spot and she runs rather rough too. Vaccum is wandering around 10-12 in/Hg @ ~800 RPM. Drastic? Nah........since I've converted from carburated, swapping throttlebodies is a snap: depresurize fuel lines, drain coolant a little, pull fuel, 2 vac lines, and a couple of connectors and it's out. Slice of cheese. But, you are right, if I can get that dead spot gone without swappage that would be ideal.

There are 2 switches: One is the 4LO switch, that's the one on the shift linkage under the boot that we are talking about. The other is mounted on the tranny, that's the 4WD indicator. They just to tell you if you are in 4WD and if your in 4LO.

Have you replaced things like, cap, rotor, plugs and wires? Which cyl is it?

I wonder if that's my problem. I got that sudden decel when I get off the throttle. I can accually feel when the idle switch kicks in and out. It's really bad when she's cold. I got another throttle body that I'm gonna swap and see if that makes a difference. anyways, back on topic...... Beutifull wagon, yourmom!

Sounds like you found the Lowrange switch. All that does is turn on an indicator in the dash to tell you that your in 4lo. Mine died a few years back, havn't found a good replacement besides the dealer, so, I do without. Ain't gonna hurt a thing.

IEEEEEE that don't give much sidewall at all.

grossgary: Are you sure what's left of that cat isn't going to freak out the A/F ratio? starkiller: If it was me, I'd disconnect it at the conector at the top of the engine.

Rusty, eh? I would get one of those Prestone Flush Kits and power flush that bad boy without the t-stat in there. That should help a bit.

Well, I went to a couple of mechanics to see if there was a way to replace my seized o2 sensor and got the imfamous gonna hafta replace the cat line. So, I checked out the cat an it appears it's mainly gutted. I can run a rod all the way through the cat without hitting anything. So, I was thinking can I just drill a hole in the cat an mount a new sensor elseware? Or will that cause the ecu to run more rich since there is some catalyst in the cat?

I am speaking from what I've read on the board, I've never rode in an RX. So, here goes: Are those struts adjustable? They might be set all the way up. Is it air suspention? I know the RX has stiffer springs, but I didn't think they're THAT much stiffer.

It was there before the conversion, but only when I was on a steep decent. She would start stumbling for quite a while before eventually dying. Would start after I leveled her out. Ok, I was just above the reline of the guage when I put about 5 gallons in, now she's just below the half mark and no more problem except she feels like somthing is holding her back. Don't know if it's just the 80+ deg weather that's doing it or what. My O2 sensor is not working too so, I don't know what the engine is doing: IE running rich or lean.

No, because even after I get off the brakes, it takes a few secconds of fluttering the throttle before she wakes up enough to move again. She accually doesn't stall. Its more like when you step on the gas, she revs initally then wants to die like a carb does when the float bowls are almost empty.

Currently, I have a good used one in there. So, the idea is on the back burrner right now. Gots other Subarus that want my undivided attention.

Man, what a differnace a 20 deg drop on the weather can do for your performance. Just came back from a test drive and WOW. She definately likes 75 degrees with a tad humidity a whole lot better than 97 degrees with less than 12% humidity. :-\ Anyways, back to my question.....How come when I come to a fast stop she wants to stall? She only comes back after I can jerk her forward. Then she's fine. What gives? I am running on about 1/8 of a tank of fuel and last time before I filled up she would hesitate after a fast left turn. Gots any ideas? This is very wierd. I swapped to Fuel injection for better reliability and mileage and yet I'm having more troubles than I did with the carby. This does NOT compute. Guess Suby wanted to stay carby. Forget it, Suby!

I don't know if the o2 sensor would cause pinging, that sounds more like timing and/or bad gas.

They are excelent. Very good quality. Had them custom build a EA82 for me. I would deffianately purchase another one from them.

I'm not sure whitch A/C unit you have but if it's the Hitachi, there are three wires that goto the the unit. There's one blue wire that goes to the compressor clutch and the other two goto the pickup coil. You want the single blue wire. Give it switched +12V. But, like NorthWet said, make sure it has adequite refrigrant and that it's accually cooling the air. You don't want to fry somthing, ya know?

Well, I swapped the coolant temp sensor with the other one I had and she's idling better. Still rough, but has improved. VAC around 12-13 in/Hg instead of fluttering around 10. Another thing I should mention is that my Air/Fuel guage is reading an open (full rich) when connected to the sensor. Too bad the o2 sensor is wedged in the cat, I REALLY want to know where that engine is running A/F ratio wise. Guess it's time to mount a new one elseware.:-\ Excelent writeup, grossgary, very good. However, my coolant sensor has a pigtail on it. Also did a oil change and now my valve tick is back. I can't win.:banghead:

After my coversion, Suby's been running a rough and I have very little lowend torque. She's now better after I got the CEL turned off (Purge, EGR and NSS), but she's running rough, I feel small surges throughout the RPM range, and she's running about 20 deg hotter than she did with the Weber. Sounds to me like a running lean condition. I disconnected the O2 sensor just to see if it might be bad, and CEL did not turn on! She was fully warmed up so, I would think she would be in closed loop mode. This don't make sence to me. Other possibility is the coolant temp sensor is shot, I do have another one laying around that I'll try. It's state is unknown, I'll hafta see what happends. Any thoughts? Well, off to replaceing a t-stat in another Suby...............................................

Looks like the oil seals are shot. I right clicked view image and had no problem viewing them. Very odd.

Ok, I'll check it out. Thanks!
