Hi all
just recently i added my bosch +4 plugs to my car now my car kinda skips at idle and in the 1500-2000 rpm range could this be my fuel pump or maybe a bad coil pack or wires ,i don`t remember this happening before the plug change but it could have been there i realy don`t want to put the old plugs back in to see if it does it then, it`s a pain in the arse to change the plugs on the 4.6 what are your thoughts and suggestions i checked all the hoses and connections they are all secure
