Engine missing out and engine light on, has 29,000 miles. Is this an ignition coil issue?

Obviously you need to get an OBDII reader or get your check engine light codes read to be advised.
After you've checked your codes, you can purchase new COPS here- https://amzn.to/2Rfp5Zd IF that is the problem.

This is a common problem with Retro Birds
It seams more so with the 02's....which I own!
It sounds like the coil on plug system (COPS) are defective. They are available here https://amzn.to/2Rfp5Zd and reasonably priced for a set of 8. Do check the codes but if this is the problem replacing all 8 is the best way to go. The symptoms you describe leaves me with little doubt of the problem. Mileage isn't necessarily the problem, the usual cause is either oil leaking into the plug ports or age of the coil rubbers cracking and shorting out. In my case (twice) my car went into "limp home mode" at 20 MPH. Tighten down or replace rocker cover gaskets if leaking. In my case I had oil leaks the first time 32,000 and year's later 60,000 just dried out and broken rubbers the second.
Good luck!

You need to get your codes read whether you do it at Auto Zone or Advanced Auto or purchase an OBD reader that meets your satisfaction. Right now you are playing the guessing game. Part of troubleshooting a car is having an OBD reader, there are others out there. Regardless of what anyone guesses, it's exactly that, a guess because you have not read the check engine codes.
