A: Hi, Jesus. It sounds like something did not get installed properly while you were working on the car. My guess is that the issue is with the way the spark plug wires are installed. Start by double-checking all of your work, ensuring that the spark plug wires are routed correctly (going to the correct coil and cylinder), and fully seated. If the spark plug wires are not routed according to the vehicle’s firing order, the engine will misfire.
Good luck!
