I failed emision because of bad throttle sensor. Got it fixed. Passed inspection. 2 months later engine comes on again this time the code is saying all 4 cylinders are misfrying.Replace spark plug coil and wires. Now the engine light is on again and all the previous coded are showing again. WHATS THE PROBLEM? HELP

The first thing that you should check is that your gas cap is screwed on tightly. Your engine light will come on if it is not.
