Cleaned the IAC , cleaned the MAF. Changed the fuel filter , car does not idle properly hangs high then drops almost dies and slowly makes it way to normal.
Must be my tune ?? How do these things happen when the car was running perfect ?? So annoyed !!!!

Is it a new development? Are all of the vacuum lines connected and tight?

It started when I swapped out my plugs for ngk
Went to my tuner to see what was going on and just got worse after that . Thought it was plugs , went back to stock , 28-30-32-34 , didn’t really change much . Tried cleaning IAC, Maf, fuel filter and still the same . Which leads me to believe my tuner sucks shit , he tweaked something and couldnt get back to normal. And didn’t give a shit . On the dyno full throttle it was great driving home on the highway was great too but stop and go car sucked . He doesn’t seem to think so .
