MaIntenance plz help
I started off putting a new motor mount
and thermostat . 5 days ago.. Took it about
five miles out of town. As I was coming
back I started to go up a small hill I started
going up the hill and my car lost power the
gauge started going down from 70 miles in
speed. The car is bogging like it wants to
turn off. What could it be? I did have the
head gaskets replaced because there was
oil in the plugs , so I did head gaskets and
new plugs now there's oil again in the
plugs . What could it be?? To lose power
