Get a code reader--please! A good stand-alone reader costs $50-70 and will soon pay for itself. Or you could by the PA-soft bundle for use on a laptop, which runs $20-30, I think. In any event, you want to be able to display live data, such as fuel trims and wheel speed sensors, in order to help diagnose vacuum leaks and ABS issues efficiently. Otherwise, you're likely to spend untold time and expense replacing random parts or trying to chase down your problems.

If you get a "check engine" light, it means an OBD code has been set. If you get the code (or codes) read and post it here with the explanation so that we don't have to look it up, we can help your proceed from there. Some code readers can reading pending codes as well, meaning that there's a malfunction detected that will set a code if it persists.

No codes at all except a misfire?

Misfire is your problem. Swap the 4 coil pack with another cylinder to see if the misfire goes with the pack before throwing money down on something that you may not need.

iirc, setting a misfire results in a code given..unless he made that up...pull the left engine cover off, count from the front 4 coils, swap 4 with another adjacent coil and see what it reads. all thats needed is a 10 mm socket.

The check engine or service engine soon light codes can be read with a cheap $15 code reader which you should have, at the very least.

The service interval is something different.

The "Service Engine Soon" light is actually the same as the "Check Engine" light, and it means that a code has been set, but if the problem has been fixed, the light may go away.
