still misses under load...again

[fixmy97gst]

Well I thought the problem was gone...It never did..so I took it to a mechanic ,he said fuel regulator, because it was reading 67 psi beetween the filter and the fuel regulator and that should be 42 psi, so it was replaced now it does it only so slightly (bucking/ hesitation)
and the mechanic is not so happy with the results...what gives on this car...I've done boost leak test and made the repairs that were leaking..replaced NGK wires ( blue wires) NGK plugs bpr6's single electrode..new fuel filter, new crank angle sensor, new cam angle sensor...plus all connections have been tested as the sensors....Hey this car has eluded 2 mitsubshi dealerships...not one of them even mention the fuel regulator..is it the ECU or the movement of the crank walk or is it hitting fuel cut eariler than specified?? ....not sure how much I have because I 've had the thrust bearings replace at the mit's dealership and was starting to C/W on the 2nd tank of gas but I disconnected the clutch interlock switch and has helped so far... Oh by the way..I have a 97 gst completely stock no after market mods...

Sounds to me like one of two things. A bad mas or a bad o2 sensor. Let us know if you find anything else.

No O2 sensors are fine...I switch out a MAF from a fellow that has a gst same thing...

I found out I have a bad weak turbo,My mechanic said...not building or holding enough boost ,he said comes on so so then about 4000 it looses psi....so I guess take it to a shop that deals with turbos to find the extent of the damage???? Or to rebuild it my self... prozac'd.....

also I have notice that the #4 spark plug has a little carbon around the base of the plug than the others , could it be the turbo not keeping up...this guy said he felt the car has less power than it should..I wonder if it is the wastgate...the turbo is quiet and you can hear the BOV work so I'm wondering...when I did a boost leak I notice air escaping out of the BOV around 5 or so psi, is this nomal????I really like this car but I am considering of getting out of the nightmare.... Help!
