I have a cylinder 3 misfire on my 2004 Mitsubishi Eclipse (4-cyl). About how much should it cost to repair? Monro wants to charge 600 and it looks like just doing the spark plugs and wires? Says will cause serious damage if not done immediately (the Service Engine light just came on today).
You didn't say how much checking they did before quoting a price.
If they got far enough to know the spark plugs need changing then why not change them right away instead of doubling the amount of work and halving the customer satisfaction.
Your description suggests they took something of a guess and you are likely to end up with new plugs, etc. whether they are needed or not. They are probably guessing it needs a coil pack also.
If it is just plugs and wires then 600 is far too high, though some types of spark plug are very expensive at retail, good discounts can mostly be found.
Genuine Mitsubishi parts are expensive but pattern replacements are much cheaper.
Sometimes it is only after replacing a load of expensive parts (instead of properly checking and testing) that the main fault reveals itself (thats a laugh) and of course they tried them and so you gotta have them because they never put anything back...
You clearly didn't trust them much and probably trust them less now. My suggestion is find somebody you do trust and add him to your circle of friends.
Certainly neglecting a misfire can cause damage and expense but most people most of the time get away with taking a chance for a short time. It depends how lucky you are as much as anything.

Run your tests before you start buying your parts. verify that your fuel pressure is acceptable. a defective fuel pressure reg., clogged fuel filter, tired fuel pump, fuel injector, loose or damaged wiring to the injector or coil, maybe water in the gas or too much fuel cleaner/additive.

idle should be self ajusting might check for vacum hoses off if not idleing proper

The thermostat is found at the end of the top radiator hose . Find the top radiator hose and follow it to the engine .There you will find a thermostat housing with the end of the hose attached . There will be 2 bolts holding down the housing to the engine. Undo the bolts and pull the housing off and the thermostat will be there.

It could be your spark plugs or a coil. To see if it's a coil move the coil from #5 to #6 the miss will change to that cylinder with code p0306 and change #1 to #3 and see if it changes to p0303. If it does replace all the coils. You change all coil because if one or two go you know the rest are not far behind

is it misfining ,or is the code just old and needs to clear?
