Default 0068 code

i don't seem to have been given any breaks with this cars,other than breaking.
i had the cam bolts back out thing(thanks nick)fixed.then boost control,7lb. springs and removing the controller took care of that.
now at different times i get a p0101 alone or with a p0068.the tc codes show up too,1278,36,93.i all so get the left actuator ground codes,b0361 and others intermittent with the A/C,reduce power mode is the bitch.one day no code next all .could it the the weather?
i cleaned the MAF,tightened the TB,found a wire on the maf harness bare and wrapped it up.map looks good and vac is -19-20 at idle.the tune visit of three i had a still issue,he turned up the idle to 1100rpm.now there is a part throttle skip when cruising.
i ,again, have no tuner.he went to work at advanced auto parts.i do however have a diablo.can i tweak the tune made with efi live?it shows 11.2 afr on the dyno.when i stat it cold it is showing steady and rich.at 180 open loop kicks in and my afr is all over the place and pegs my lc-1 moats gauge to7.4 WOT.i put on another wide band on the road and saw 10.4 WOT
this is allot to read but i could again us the help.

For the reduced power 0068 code ( which brings in the 1278 ), go to the engine diagnostics > 1514/0068 table and raise the values until the problem goes away. 4.10 is the max value. This table is a safety mechanism in the event the airflow doesn't match the predicted values. To the PCM, this would mean the throttle body is stuck open. Since you're F/I, you're exceeding the predicted amount of air flow.

Well, get out your favorite country album and get back on the HPtuners bandwagon or take it to a good tuner. It's not a difficult or even time consuming fix.

Did you change the table yet? If not, it's going to keep happening until you do.
