i had a compression test done and it was 144-155. when i get the car up to 35 it shakes and has a loud noise . it chokes going up hills also.
i had a scope test done.
so my question is is this worht saving or is this a fixable problem?


Answer
Were all the cylinders reding between 144-155 ?. If they are, Your problem may be that they have the wrong spark plug wire on the wrong spark plug. Check it.

Other that this, I would need to personally see the vehicle.

QUESTION: Does the CHECK ENGINE light ever illuminate while driving the vehicle ?.
