I do every possible thing to my contour to improve gas milage, but its getting WORSE!!!!

Today, odometer reads 204 miles, Gas tank = almost less than 1/4 left of fuel.

I checked compression, getting around 135 range.

Changed spark plugs recently, changed Ignition coil due to a scope showing some weird things with mine

Checked o2 sensor at school, the comptuer correctly reads it

PCV Valve has been changed

Oil correctly changed, Transaxle fluids changed

EGR Valve NOT Opening, but I am told that shouldn't make my gas milage suck this terribly!

Do not excessivly idle, Air filter is clean, air box is tightly installed. New MAF.

Fuel injectors cleaned

It idles alittle rough when she has warmed up around 10-15 minutes of usage, vibrates terribly at stop lights when warmed up.

Im thinking my timing belt is slightly off... This is pissing me off though....

I unplugged my A/C Clutch for winter, so I can use Defrost without my A/C stealing power from me.

I have used VERY gentle driving habits, I havnt red-lined the engine once on this fillup.

Anyone have any suggestions?
