i have a dip on idle as in a slight dip in revs and lower tone.

any ideas just changed the coilpacks going to check the plugs tomo
should of dont that while i did the packs DOH!

its def not the maf

 

Mine did this when i found out i had done a head gasket. Might not be the case with you though. Maybe i should just keep quiet if i cant help.

 

Also check pipes/dump valve on the intercooler. This can cause idle to hunt etc.
