Yeah I really do want to lower it eventually but now I have bigger problems. I traded a Honda Civic I had for this and been putting money into it every since.

The new problem is this PO305 cylinder 5 misfire. Okay so I pulled the plug and it had water on it I sprayed it out, did pressure test found no leaks around intake... I cut the code off and am going to see if it comes back on if it does and doesn't have water I'm going to replace spark plug. If it does have water im going to have to replace intake manifold? The code hasn't came back yet. Idk where the water came from.. I know if you switch to another and it does it it's probably the plug wire. I'm going to wait a week while monitoring codes and see if it comes back. If it does and doesn't have water im change plugs and wires.

Cylinder #5 like the one closest to the driver’s side front of the car?

Clear the code put the plug back in run the engine for a while pull the plug back out and see what it looks like. or if it throws another code

Is it blowing any smoke out of the exhaust?

If so check the cooling system (Pressure Test)

I've been driving it for a few days now the code hasn't came back on and there's not any fluids built back up yet. There hasn't been no smoke coming from exhaust either. If I do have to replace intake manifold which one would be the best? I think it's been replaced before because it actually does have the aluminum coolant crossover. I wish I could find an all aluminum intake without having to switch to pi heads.
