My check engine light came on I had my codes read and it was a misfire in cylinder #2. Ran sea foam through engine & I changed my spark plugs and found a cracked spark plug in that cylinder. Changed spark plug wires, changed oil w' lucas oil stabilizer. After doing all this my car ran awesome! For about 300 miles. Now it is sputtering right after I start the engine then stops sputtering once I start driving. I always use premium gas as recommended, and fuel injector cleaner every other tank. I always let it warm up for at least 10 minutes before driving because I live in a cold climate. My check engine light came on today when I started it. I went to check my codes again and none came up. Please Help!

The intake butter flies are not in the 2.0L motor in the 626. One thing I would try right away is spraying either brake cleaner or carb cleaner around the intake manild/cyl mating surface. They are famous for having leaky intake gaskets. Also have another look at your plugs. If there are cracked ones again, you might be looking at a coil, but check the intake first
