What to do next?

Change plugs and coils.... All of them not just the one

Ditto, what EXICA said.

Check carefully for a coolant leak from the heater hoses.

How do you fix a coolant leak?

Depends where it's leaking. IIRC, the typical leak over number 4 is the heater hose, which would require new fittings, or hose, or heater core.

I think I have a slow leak. I've been putting water in the coolant to keep it up to the line every 3-4 weeks..

I'm changing out the spark plugs & cops this week but probably should find that leak... Does coolant slowly evaporate over time if I'm putting water in there?

Go to Pep Boys, autozone, advance, whatever, and rent/borrow the pressure tester. When I did it, I also had to borrow the threaded adapter kit to attach to the degas bottle (reservoir). While you're there, just get the $5 cap. (That's what was wrong with mine - it would not hold one pound of pressure.)

Pressurize the system to no more than 16 pounds, and a) see if it holds pressure, and b) if it is leaking, hopefully pin point the leak.
