Got a flat spot! Need help! Got a '00 SS manual with a flat spot around 3000-3500 rpm or so. The car is bone stock with 54,000 miles and there is a definite flat spot where the car is not getting enough fuel. Also at about 4,500 rpm the car begins to make a noise like it is starving for fuel. It's an unfamiliar noise to me but it sounds like the engine is either starving for fuel or there is not enough spark. I plan on changing the plugs but any thoughts on why this thing would be out of fuel?

Start by taking stock of the intake-side mods. The
'00 respond poorly to a lot of the "old school" LS1
trickery type stuff. Not to mention that their lean
tuned nature probably doesn't like a dirty or greasy
MAF such as 5 years on a K&N filter might produce.
Even if the MAF were unmolested.
