MERCURY MYSTIQUE COMPRESSION PROBLEM

1998 Mercury Mystique

I have a 1998 Mercury Mystique Sport 4-cyl that spits and sputters and then shuts off. I've taken it everywhere (incl. Dealer) and no one can find out what is wrong with it. I have replaced the fuel pump and lines, as well as the plugs and wires. What else could be causing this?

Start by checking compression. Sounds like possibly a timing issue. Or valves
