If it is an ignition miss, it should turn the check engine light on and give you a code for which cylinder.A fuel problem or mechanical problem would not always make the warning light come on. Once the engine warms up the O2 sensor gives the computer data to cut back on fuel.You might want to check the computer for trouble codes to see if anything has been stored.

Hi there:The white smoke is a sure indication that water is getting into the combustion chamber, and this would typically be indicative of the head gasket failure or a related head failure... namely a warped or cracked head.There is nothing that you are going to be able to pour into the cooling system that will be a reliable long term fix. While you may cut down your smoking some, the reality of it is that the cooling system will generate upwards of 15psi when operating properly, and any "liquid fix" is going to fail under this amount of pressure. The failure is a physical failure... be it a deteriorated head gasket, a cracked head, or a distorted/warped head, it is a physical failure that liquid simply can't permanently fill.This and othefr details could be find in THIS LINK.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.
