Well, it started!
But have to investigate more.
Does not idle nice, and pushing gas has no effect...so that and the
extra bolt....I must have left something unhooked!

 

What about the strap for EGR pipe about middle if pipe/manifold??

Make sure you have the brake booster hose installed, along with all the ducting from throttle body to the air filter box.

If you unplugged the connector for the throttle motor, then you need to insert key to ign,,, turn key to "ON", and then back to "OFF" within 2-3 seconds...... wait for throttle motor to cycle and count itself, you may hear click/clunk when blade drop shut... then start engine.

Been a number of instance where plenum gasket installed wrong,,,, Vacuum leak.......

 

I took it all apart again, and I think you are right...I think it was the clamp for the egr pipe...about middle. But..that doesn't explain the poor performance. I would like to check the spark plug wiring. I'm sure if I had it wrong, one length would have a LOT of excess...but if the front is from left to right...cylinders 2,4,6...which cylinders in the rear do the wires go to (from the plug/coils in front.
Very bizzare...the way it was, it would start right up...idle rough....tough the brake would stall the engine, hit the gas would do nothing. Something must be REALLY hooked wrong, or just left unplugged. Gonna re-assemble again tomorrow.

 

DID you replace wires ? DID you use OE Hyundai wire set ?

Standing at radiator and looking at engine :




B ====== 1 --- 3 --- 5
E
L
T ====== coil 2, coil 4 , coil 6

----------------radiator --------------------

 

Yes, I used new wires that I got from Hyundai.
So I see your diagram, but I wanted to verify where
the wire from coil 2,4, and 6 go.
Is it to its' partner on the other side (1,3,5)?
I don't think I could have messed it up, but I want to verify
in the morning.

 

Look at pic in this topic --> https://www.hyundaiforum.com/forum/s...ead.php?t=9203

The Hyundai wire set has a #1m #3m and #5 painted on the cord, so theu go where they is numbered, install them the same way they was removed.

You will notice when you get to Bank 2, you will have short length hanging, a medium length, and a long length.. install to the coils accordingly.

 

OK...I saw the numbers on the wires...so hook 'em as indicated 1,3, and 5..then what is hanging...longest goes to 6, then 4, then 2. I will double check that this is the way I did it.
Thanks!

 

Looks like 1 goes to 4
3 goes to 6, and 5 goes to 2???

 

Verify your wires is routed and clipped as shown, the lengths hanging will tell you where they need to be.. I suppose that next 3.5 we get I should take better pic of wires as they come around the bend from the rear..

I made crude drawing as to how the wires is correctly routed from Bank 1 across top of engine to Bank 2..

 

I took it all apart, verified the spark plug wiring is correct, and put it back together again. Same result...
But I am thinking I know what I did wrong.
During the first disassembly, I mistakenly took apart the part shown below. I thought it had to be removed to lift off the intake manifold. I think it had spring tension of a little gear inside, and no longer does. I took it apart again to verify.
Do I need to replace this part, or can it be re-sprung?
It is on the top, passenger side of the intake manifold (see pic below) I don't know what the part is called.
