Cold Starting ?????

Since I cleaned my throttle body with Mopower Combustion chamber cleaner, my truck has Idled a little higher (1-2 rpm) than normal. I tried using some more cleaner and installed new spark plugs , thought that there may have been a peice of dirt caught in a injector or the plugs were fowled up. Now when I start my truck when she is cold it's like she start in a lazy way......... once the truck is warmed up she starts like normally. I just recently had the fuel pump replaced, I figure that there must be more dirt caught some where in the injectors or the throttle body ???? any comments or suggestions...... v8-318
