See if you can run a scanner on it. Could be a bad coil.

Check the spark plug gap. Make sure plugs and cop are installed correctly. You could have a dirty fuel filter or bad fuel injector causing it to be lean.

The manufacturer recommendations should be on the fan shroud.

If its multiple then it could be a bad fuel filter or fuel pump.

Under your car, between the rear axle and fuel tank.

We figured it out.. I think lol because it isn't missing anymore but I think when my cousin put his side back in he didn't make sure the boot was put on the plug then put the cap and spring in at the same time to make sure the springs were touching the plug also so we redid them and everything's going good now

Well then hopefully that's all it was. Lol. Sometimes we all overlook the simplest of things.
