My aunt's car keeps giving me a code 2302 and the car starts to miss really bad.
I changed the ignition coil, plugs and wires and the manifold gasket.
It runs fine at first but then after the engine gets warm and I go to take off, it starts to miss and give me the 2302 code.
I clear it and drive it again and it starts to miss while changing gears.
I'm about to lose my mind.
Please help.

Good afternoon,

I would first start with a compression test.

I attached the possibilities below and a flow chart for you to follow.

I attached the testing for this. There are a couple more causes of this so we need to run through this and see what we get. Let me know if you have questions on this and we can go from there.
