That depends on what engine you have since there is no 2.0 as you posted. If you have the 4.3 V6, the cap is at the back of the engine. If you have the 2.2 4 cylinder, it doesn't have one. It's a DIS system.

Yes, it could be either of those or even a bad coil.

There are 2 coils and they are on the back of the engine. All you have to do is follow the plug wires.
