I WANT TO KNOW WHAT THE NEXT STEP IS IN ORDER TO FIX THIS PROBLEM. DO I NEED TO GET MY MECHANIC TO FIX OR IS IT AN EASY TASK THAT I CAN TAKE CARE OF? IF SO, WHAT PARTS AND/OR MATERIALS IS NEEDED? AFTER THE DIAGNOSTIC TEST, MAP/TP SENSOR ALSO SHOWED UP ON THE MACHINE.
PLEASE RESPOND AT YOUR EARLIEST CONVENIENCE THANK YOU DAWN UMBEL

Re: CORRELATION VACCUM LEAK P0068
P0068 - Throttle Body Airflow Performance (PCM) (Vacuum leak) Take a can of carberator spray and spray it around the unpper intake area and near the throttle valve housing, listen for the engine to make a different sound, when it does you have found the leak. It may be minor or major there is no way to know. If you can't find any vacuum leaks replace the MAF sensor.

code p 0306 is --misfire on no 6 cylinder ===causes injector wiring ---ht leads , coil
code p 0449 is EVAP purge valve --circuit malfunction ===causes --wiring--EVAP canister purge valve --ECM and code p 0068 is MAP ( manifold pressure )sensor ( mass air flow sensor (MAF)---throttle position correlation===causes --wiring--MAP/MAF sensor--mechanical fault
could be a common wiring harness plug connection or loose connections on the ECM
(in this my example is done on ford, however it can be performed on any make and model) Being unfamiliar with cars can be a great pain in the ***. Especially when changing spark plugs, and spark plug wires. If not familiar with specific vehicle firing order the best way to prevent cross wiring, and confusion is to change them one cylinder at a time. After purchasing the spark plug wires the first thing that needs to be done is organization. I like to sort the wires from shortest to longest, matting the like ones as I go. This step makes the next step a lot more simple than going at it unorganized. Next as you are taking off an old wire simply match it with the proper length, and replace it before moving on to the next one. Since you are doing this one by one, taking the old one, and comparing it to the new one will be a great help to determine what length to use. Don't pretend to be a wizard by removing all plugs, and wires at once acting as if it is an easy task to remember where they all go. The only easy thing about this task is realizing how easy it is to mis-wire your vehicle. After you come to this realization the next thing noticed is how difficult it is to wire a vehicle correctly without taking my tip and doing it one step at a time....
One more great tip before I end this, always check for proper spark plug gapping. You can do this by purchasing a feelers gage aka spark plug gapping tool. Purchasing one is even more easier. All you have to do is go to a local parts store, and buy a tool that fits right on your key chain!!! How simple is that?
Code P0123-THROTTLE POSITION SENSOR 1 CIRCUIT HIGH and code P0068-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION. Without having the vehicle to properly test, and based on the information I have it sounds like your throttle position sensor has kicked the bucket. Replacing the sensor with a new one should solve your problem.
I really don't have any greatly detailed step by step procedures here. In the pictures below is you can figue out how to remove the different items (cover plate, cental console...) do it in order by number stated below the picture. Also in the laxt picture, there is a picture of the SRS-ECU (electronic control unit for the airbags). Be VERY VERY careful not to jar it or bump it.....be careful on other words. Make sure you disconnect the negative battery terminal before you start but there is still stored energy in the vehicle and on your vehicle I have seen a couple of times when the SRS-ECU was bumped the air bags deploying by accident. I have some factory Mitsubishi service manuals on PDF at my shop and if I remember (I'll try), will look to see if there is anything about removing the center console & will post if there is anything. The other stuff is pretty easy if you are mechanically inclinde. Hope this helps a little anyway....
