My Honda pilot makes a sound that gasoline is not going through, wants to stall, takes a few seconds to be able to accelerate. I changed the spark plugs and added a gas additive to clean the gas. Two lights come up the check engine and vr4 light when problem starts, what could be the problem?

Pull the computer codes and it whould tell you what's wrong (it might even tell you exactly whats wrong)... I'm taking a stab at fuel pump or fuel filter , but you NEED those codes...you are wasting money replacing anything before you get the error codes off the computer.

Smoothy's right....you have codes coming up for a reason. Have them checked and go from there.
