Default Few probs with the LT1

Alright, first off.. it takes forever to start.. and sometimes I really mean, like 8 seconds.

I'm feeling a wierd feeling from the rear of my car, especially at low rpm's, and another wierd sound that I can't describe that comes especially when I am turning the wheel a bit(mostly at speeds above 30-40), even like a curvy road. I think I am feeling more impact from bumps too, and the rear might feel like a centimeter lower(I could be imagining ****). Also, I don't remember seeing this before, maybe I didn't pay attention, but the little thinish(1 inch or less) metal type thing that runs to the rear left hub is in a different position than the one on the right.. I don't even know what this thing is, is it supposed to be symmetrical?

And last but not least, completely randomly my car will lose a certain amount of power(kinda similar to losing a cylinder)... it happens randomly, it doesn't go off and on, it just switches one way for a min then (especially if I rev it or something, then go), it goes back to full power.

Help me fix my baby...

Run throught the entire motor from Fuel filter to adjusting the rocker arms to a hell of a tune up. Spark plugs, wires, Cap rotor, Air filter but this problem sounds egr related. It could be clogged full of carbon or the egr solenoid is not working properly.

I don't have egr, I changed fuel filter less than a month ago, same with plugs, wires.. I take good care of her. I think I broke something in the rear suspension area.

Change the fuel filter again. Sounds like the fuel pressure reg. Could be the fuel pump, the check valve could have failed.

sounds like an opti spark. 9 times out of 10, the opti spark is what's wrong with the LT1. I've seen opti sparks straight from the dealership that went bad in 2 days.
