I think J suspected a fuel delivery problem right?
And BTW, you owe me the money in your purse.

I saw those rear tires when he was here before this major malfunction...and uhhh, he's already been doing plenty of that! I can't IMAGINE what that new and improved power feels like at the throttle...man

Ordering my longtubes, two Magnaflows, and an x-pipe tonight. No comment on the cats, since it's illegal not to have themBTW, are you gona just not use cats anymore, what about inspection (not that you can't get passed somehow anyways)
Haha, it's not. I'm going to TRY to take it easy until I rebuild the trans. The rebuild kit is about $1K that will hold up to about 650hp.
I gotta gather the funds for a new set of tires first. The current rear tires don't have much life left on them, so I have to take it easy for now. But when it's time for new tires, it's on

No, the very first thing Justin said was that he thought the cat was plugged. Didn't he tell you to remove it and come back? As I recall it still wasn't an injector problem, you knuckleheads did that on your own when checking everything out
Since it was different from bank to bank, and worked before hand, he was pretty sure it wasn't fuel delivery.

He did mention the cats as his first diagnosis.
We had a bad pin on an injector plug which we weren't aware of at the same time we were diagnosing the p0300. When we pulled the cats, the engine was still idling and running very poorly due to the bad injector plug we didnt know about, so we figured the cats weren't the problem. The pcm finally threw us a p0200 injector code later on which BOSS found to be a pin coming loose from one of the injector plug terminals. It didnt hit me until yesterday that removing the cats the first time didnt really tell us anything since the one injector wasnt working.
He did.

Not true! I swapped the plugs and pulled a 303 #3 misfire. Thats when I hit the #3 with the noid light and noticed I lost light when I gave the injector cable a gentle tug. By reseating the individual cables into the harness, I got the connectivity back.
Cough it up
..... I need a new SC B

There were not injector codes until after you started messing with it....cylinder 3 is on the driver's bank which was running just fine...the passenger side was the one having major problems

Sweet, glad you got it fixed man!!!

Don't forget, the driverside went lean and the rough idles started when Jeff was 20mins from my house on his way back to Austin. It was then that we checked hoses, wires for burns etc. We hadn't pulled any cables.
I'm not trying to be sensitive here, but I feel clearly there was an injector cable or harness issue that I don't believe JK nor I caused.
SO, with that said this is the entire chronological breakdown of what happened as best I can remember. You can make up your mind if you want to give me that money in your purse
Got tune - Justin showed lean on pass (AFR is on driverside)
No codes reported
Leaned out on the driverside/rough idle 20mins after leaving BOSS's house
Checked hoses for vaccum leak, checked cables
Removed cats
Checked springs on pass side
Jeff drove back to Austin at this point
I replaced o2 sensors
(still lean, rough idle)
Bought me a code scanner!
Pulled open injector circuit P0200 and P0300 multiple misfire P0300
Cleared codes
Pulled open injector circuit P0200 and P0300 multiple misfire P0300
Cleared codes
I replaced the plugs
Noticed #4 plug was much darker than the rest
Pulled a P0354 code - ignition coil d malfunction (#4 cylinder)
Cleared codes
Pulled a P0354 code - ignition coil d malfunction (#4 cylinder)
Cleared codes
Changed #4 coil
Pulled a 0303 misfire on #3 cylinder
Cleared codes
Pulled a 0303 misfire on #3 cylinder
Cleared codes
Checked all inj and plug cables
Pulled a 0303 misfire on #3 cylinder
Cleared codes
Noid light on #3 - light blinked ok/light dimmed with light pressure
Reseated pins into injector plug
Bingo..no more lean on driverside, no more misfire or open circuit
JK drove back to Austin
JK found vac leak at egr
EGR removed
p0300 codes reported for misfires
JK removed cats
no more p0300!
So as JK said, he and I were not aware of the p0200 or the p0300 because it was midnight and neither of us had a scanner at the time. I do think it's strange that a an open circuit and misfire showed up out of the blue when we didn't pull any cables. So, all in all, our removing the cats did no good - because there was a problem with the injector cables, specifically #3.
That's my diagnosis anyway. Take it for what it's worth...just an educated guess as I am not the expert.
