Well this well take some time to explain this....

A haynes manual would be needed with this....( dis connect battery)

1st.. Remove the upper intake, un hook all line to the TB and vac. hose's and remove the front spark plugs wires .... (see repair manual)

2nd once u have it off then u will need to bleed off the fuel presser at the valve tee on the belt side of the motor... Then un hook all injector plugs.. and remove fuel rail, there will be a line that go's to the fuel presser regulater u will need to un do this aswell....

3rd reverse the process that i IN short describe for ya...

I hope this give's u and idea on the steps... the rest u will need to refer to the manual...
