I put new plugs and coil packs on my car. It runs but it slowly gains speed. What's wrong with it? It doesn't have a catalytic converter and my oil isn't mixing with coolant. This car doesn't have the supercharged engine.

If the issue suddenly appeared after your repair, check the following:

  1. Did you use the correct model of spark plugs?
  2. Are the spark plugs correctly gapped for your engine?
  3. Did you use the correct ignition coil for your engine?
  4. Did you reconnect the correct spark plug to the correct ignition coil output?
