Starting problems

["chris " <chris@xxxx>]

I am having problems starting my car, it does the same if its cold or 
hot. I start the car with the gas pedal depressed 1/4, the car starts 
revs up to 2,000 then go back down to 0 no mater what i do to the gas 
pedal. It take 2 or 3 goes to get the car to run. Also the cat is 
still glowing red, it back fires sometimes, i think its in the intake 
manifold. The plugs are sooted black. I am assmuing the CO2 mixture 
needs adjusting? 

Thanks
