So I have changed bout everything but I still have high LTFT bank 2 bout 15% at idle and just got code 2006. 1500 rpm it struggles but good power at other rpms. At idle it has a random puttering... any help please!?
maybe IMRC actuator?

 

Yes. Replace the IMRC actuator. That's usually the cause of that code

 

Ok still chasing issues. at idle in park engine has a random shiver then rev to bout 1700 rpm it has rough shaking then smooths out above 2000 rpm. But...... when driving it neither problems show up at those rpms??? But...... with cruise on at 70mph I get a intermittent bog like your driving in headwind and wont shift down so not sure what to think or should I just drive it.
I have no codes!
i have changed plugs
intake manifold gaskets
Fuel filter
fuel injection pressure sensor
drained pcm battery
Ran a can of seafoam

Cleaned maf and throttle body
o2 sensors look to be operating correctly
sprayed for vacuum leaks
ANYONE HELP PLEASE??
