HAHAHAHA
I'm not sure how the car would react with them removed and not functioning. Not having functioning EGR i can see being a problem. EGR will dilute the air mixture which means the engine would run rich if it we're getting any exhaust gas but thinking it was, or could run lean if it was getting exhaust gas but not knowing it. A bad EGR valve can cause some horrible backfiring and stumbling on engines. I've never dealt with one on an LS1 but i have had one stick on an LT1, and a couple other engines.
You can completely tune out all of the emmissions things. Are you running a computer that is even tuned for your swap? I cant rememeber i'm sorry

But really SIX pages of BS all because this guy is too lazy to finish his project.
Yur lucky the junk runs at all.
Finish the wiring correctly before you tune out a bunch of stuff you MIGHT NEED!

A rich running engine can foul spark-plugs after a while. Have you checked the plugs? Plugs will trigger a P0300 misfire code though.
If the engine is down 1 or more cylinders completely (never fires), the ECU may not throw a misfire code. If the engine is stock but sounds like it has a cam lope, you're down a cylinder or two. While the engine is running, unplug coil connectors one at a time and listen for a change. If one is unplugged and there's no difference, you've found a dead cylinder. Might be coil wiring, might be a plug wire, might be an injector. The LS1 injectors have a tendency to stick closed if they are left sitting with fuel in them for a while. Tapping them lightly with the blunt end of a screwdriver will usually free them up. You can check their operation by placing your hand on each one individually while the engine is running and feel for the "click" with each cycle.
Good luck

Nope after getting them first time I did clear them, now tomorow im going to check what codes it poped out again...
My gear box was changing from 1st to 2nd then 3rd on D, but then suddenly it stopped and I have to manualy do it... so Im going to check maybe the connector poped out?
I felt my injectors today for a click... and I couldn't feel anything...?! is the click really slight or should it be easily felt... cause I didn't feel ****...

If you can't feel the injector operation, you can listen to them by placing the blade end of a large screwdriver against the injector body and your ear against the blunt end. The injector cycling is a very apparent click-click-click-click. . . .
The fist tell-tale of a cylinder being down on a stock engine is an idle chop or uneven sound. Stock motors idle very smoothly. Engines with really big cams are harder to tell. Does your motor idle with a smooth sound? Or does it chop a bit? I usually check for cylinder firing first by unplugging coil leads, and then verify the injector operation of any down cylinders. If the injector is found to be working, then that quickly narrows the problem to the ignition side.

ok, update, I made another diagnostic, and I had a couple of codes... my MAF sensor still says low frequency, so that should be checked again...
But whats happening now is that my 7th piston is not changing any feel of the engine when I unplug the Coil off, but when I checked the coil it did give an electric pulse to the wire.. and when I checked the Injector via an injector tester it did give an OK (which means its good when the car was on ON) but when I started the car it stopped responding so what I actually concluded is that my sparkplug is actually dead... cause when the car is ON the injector is OK, but when it starts is when the injector stops responding...
What do u guys think? Im going to change that sparkplug tomorow to check whether its the reason...
I have some FAN RELAY, AND EGR codes which I need to delete via HP Tuners, I did go into the ECU using HP Tuners and I went into the On/Off option, I did put the OFF button on the fan relays and everything else, but when I rechecked for codes all the fan relay codes plus the EGR poped right up again...!!! what did I do wrong? how do I save the settings?!
Thanks

I read through your thread. If you are looking for compatible parts in the Middle East, I gotta ask. Can you buy a Chevrolet Lumina or Caprice in Lebanon? They run GenIII and GenIV SMall blocks, aka very similar cousins to your LS1.. In fact the 2003-2004 Lumina and Caprice is basically a 2001-2002 Camaro LS1 with a different oilpan, and very few other differences in sensors.
What year Camaro did you get the motor out of?

what am i suppose to get from this? are you askin me what year is mine??
in this case its a 2004 gto
