Engine Performance problem
1990 Chevy Lumina 6 cyl Front Wheel Drive Automatic

I recent switched out a motor in my 1990 Chevy Lumina as I was trying to fix it up to drive it. Well the first time i drove it all was well drove it about 20 miles and parked it to go into a gas station. Came back out and started it and it suddenly started to sound like a lawn mower. Found out later that a spark plug had blown out of one of the holes and another was loose. How bad is this and how hard is it to fix as I would like to sell the car?

Hi:
If the plugs just came loose, just tighten them. However, if the threads stripped, you will need to have machine work done to the head to place a helicoil in it.
