Ok So Recently I Replaced My Crank Pulley Because It Fell Of On The Freeway But I Fixed That Now. But For A Week My Car Would Run Fine When Cold But Then As It Warmed Up It Would Sputter And Lag. It Would Rev Fine In Neutral But Would Sputter While Moving Now It Does It Even When Cold I Need Help Any Ideas Where To Start???

Yep. Apparently I need to make a sticky because I say this probably once a week:

Check all sensors and connections.
Check spark plugs (read the tips!).
Check spark plug wires.
Check timing.
Check for vacuum leaks.
Check your crank pulley.

Ive Cleaned All Connections A While Back And Even Replaced Some.
I Bought New Spark Plugs And Gaped To Spec(old Plugs Had Signs Of Running Rich But That Was Due To A Bad FPR But I Replaced)
New Cables
