I just did a tune up on my 1992 Mitsubishi Eclipse. The engine started shaking about 4 days ago, and prior to that it was just fine. The engine itself seems to be running just fine, but once I put i

anytime you do the self-diagnostic you will almost always get those 2 codes.

well the low cost way to go first would be to try and change the trans fluids. If the problems still remains the it may be an internal problem

SOURCE: crankshaft position sensor location

Hello. One way to check if it is working is when you try to start the car does the needle move on you tac? If not then your crank sensor is more then likely the problem. It is located on the backside of the engine under the intake manifold. If is in about the center of the block. There will be a 10mm bolt holding the sensor in. If you decide to change it yourself (not to terrible of a job) unplug the sensor, remove the bolt and spin it back and forth slightly while pulling it out. It may be stoburn and you might have to work at it for a little bit (not a done of room) but it will come. When it's out the sensor will be shaped kind of like an L. I have changed a few of these over time and they can be a little stoburn. To install just reverse the process.

The behaviour of the car is a clear indication of turbo pressure failure and the error codes support that:
CAN COMM = communication error in the sensor network.
VGT CONT. PRS. = the solenoid that controls the turbo's pressure is faulty or the pipes that connect to it are shot
EGR POS. SNSR = the vacuum sensor is defective.
Check all the air pipes for leaks - replace if necessary. The replace the vacuum sensor and control solenoids, located on top of the engine, drivers side between bulkhead and inlet manifold.
