We have a 1998 T4R with almost 200K miles. It is running very rough and using a lot of gas. It has been suggested that there is to much oil coated on the engine from a small oil leak around the valve cover gasket. My question is can oil getting on the spark plugs cause the engine to run really bad and use a LOt of gas? Also can it be a fire hazard? The spark plugs have been changed recently and one coil. The shop we took it to wants to charge almost 1000 doallars to change the valve cover gasket, new spark plugs, wires, pcv valve, and BG fuel induction kit. Also something called Import Direct (IDI) whatever that is for 136.00 dollars. I need some suggestions on what to do to get my 4runner to run good again.
