Salute to another departed SR

[doridori23]

You posted earlier that you had a ton of smoke from the engine bay but there was no follow up to that. Was is water vapor or smoke and what did it smell like...

[redtop91]

The only way I knew there was smoke was because it was floating up in front of the headlights that night. Since it hasn't been driven. It definitely wasn't water vapor which hopefully means it isn't the HG...

[drift donkey]

I popped 2 of those damn SR's and a 4a-ge this month, so your not alone!

[redtop91]

LOL. Well that's encouraging... I guess? Life goes on after huh? I don't think it's dead at this point. Just f*cked.

you have too much money, do it right the first time. i have a ****load of white smoke coming from my exhaust and cant figure it out, i too noticed it was really bad at night sitting at a stop sign from my headlights. i have a cometic hg and arp studs so i know it cant be my hg, could the turbo seals going out cause this? if i were you man id just go balls out and check every little bolt and washer on the motor for somthing wrong, maybe you have a cat stuck in there

[hungryjoseph]

bad coilpack harness?

[redtop91]

Definitely a possibility. I forgot when I wired it up if it was connected to the main wiring harness though. I really don't feel like yanking the whole thing just yet.

[hungryjoseph]

the coilpack with the corrosion on it, was it on the cylander that was having problems? maybe it had a bad ground, or something electrical. just throwing it out there

[redtop91]

Aha. I made a critical blunder. When I was pulling the spark plugs and saw the one fouled up I didn't note which cylinder it was. =/ I have a spare coilpack harness if that is the case though.

[hungryjoseph]

you might want to check your lines for the turbo, just in case someone hasnt already posted this, and the turbo itself

[redtop91]

Yeah, turbo is one of the things I haven't checked simply because I'm replacing it soon. I don't see any leakage from the lines but I will check tomorrow. I'm starting to think more and it's beginning to seem more and more like a vacuum leak although if there was a vacuum leak and it was causing the rich condition, wouldn't all the plugs be fouled rather than just 1 or 2?

[hungryjoseph]

perhaps that one injector was dumping too much fuel? injector wiring issue maybe

[redtop91]

Ok so I finally quit being lazy and went out for a full diagnosis today and I find myself getting ready to check the ECU for codes, now I'm pretty sure you put the key to the "Acc" position, then turn the screw 1/2 turn counterclockwise and then 1/2 clockwise, or something like that, but I want to be clear so can someone verify this?

[onecrazyfoo4u]

I think the key has to be to the 'on' position, but not running. Then you turn it fully open, wait at least 2 seconds, then fully close it....then it'll give you the codes that are stored, or a 55 if there is no codes being thrown.

[redtop91]

Yeah. I just can't find a philips small enough for it now. Another thing. By default it is fully clockwise correct? There wouldn't be any need to mark the position of the potentiometer would there?

[redtop91]

Hahahaha fuggin motor. Code 55. Right. I'm supposed to believe everything is all peachy? My as$.

[IanS]

Ok, lets run through things again, what are your symtoms, be as specific as possible. Im sure we can figure this out

[redtop91]

The car idles really rough. At a stable RPM but a lot of vibration. The engine shakes a lot. One of the plugs was really fouled, and fire had burned through the catalytic converter. Yesterday was my first real day of troubleshooting. Found one of the plugs to be cracked. Replaced it praying it ran right, no luck. Next was compression. Fine in all four cylinders. Next was resistance to the injector, checks out. I'm putting off tracing the wiring back from the coil pack harness as far as possible. Don't feel like getting into that.

[IanS]

hahaha, I know the feeling, have you tried moving the coilpacks around, is it always the same plug thats fouled, or does it follow a coilpack, next, try moving the injectors around, see if the fouled plug follows an injector, if the fouling is limited to one cylinder regardless of injector change or coilpack change than it is most likely a wiring or ECU issue. Good luck

[hungryjoseph]

does it sound like a wrx when it's on?

[redtop91]

Not yet. I did notice some corrosion in the number 2 cylinder coilpack and harness plug though. Which seem to be the cylinder with all the problems. Ionno.

Yep.

[s13tulsaok]

who done the swap???

[redtop91]

Me.

[homeslicej2]

Ryon, it looks as though you're going to have to start trouble shooting your wiring ( yes, it sucks). GL man.

[redtop91]

I'd rather buy a whole new professional harness than start hacking away at mine. It only causes more problems down the line...

[homeslicej2]

true. How much would that cost if you don't have cores though? I've seen some figures for new ones that were liek $700 Maybe you can just have them fix yours. If they do it right you shouldn't have any problems.

[redtop91]

True that. I'm calling around and seeing what repair figures are looking like.

Auto wiring isn't for everone, but some people take to it like fish to water.

I'm lucky to have had a good teacher. I learned a good deal, and it helped me in some of my own side projects because I could just do what needed to be done and not had to have someone show me or do it for me.

[redtop91]

Truer words never spoken. It definitely isn't for me. I did a pretty good job on it myself but that really was a fluke, I could never hope to repeat it with similar results. This is actually the only problem I've really ever had since I completed the swap, but I really don't like wiring. I mean really don't like it.

[CoupedUp]

Hey Ryon, I might swing by when im back in town come this next week.

If we cant find a problem. I do think that Yuri does "wiring corrections" for a said price. Ever think you might have a clogged Cat?
