ok so my code said misfire in bank five replaced coil pack and plug just in bank five and cleaned throttle body and replaced pcv valve,,,truck still idl'e rough the throttle body was definantl very dirtl how do i remove the iac vavle is it the one with the gasket on it on the top left intake with a plug also going in it and do i remove it and clean the inside with a carb cleaner,,,,if i do the fuel filter how do i depressurize,,,thanks

 

IAC has a plug, yes.
Carb cleaner works well.
Open the fuel cap to release most of the pressure.

 

my svs light just cam back on, i did replace the spark plug and coil pack in bank five like the scanner said,,,misfiring,,,it's much better on the highway but i guess the light coming back on means there is still something wrong,,it does still idle very rough,,does the iac valve have 2 screws and a gasket on it also,,,should i clean that and replace all the plugs...

 

Yes; 2 screws and a gasket. It's easy to clean so go ahead and try it. What is the new code?

 

make sure u didnt knock the injector wire off when u pulled the coil out i know i have done that before. also u can get u a long screwdriver or something to stick against the injector while it is running to see if you hear it clicking spray some of that carb cleaner around the intake while it is running see if you have a vac leak. it should have a lean code or o2 code if that is the case
