I've had the same issues, replaced spark plugs and cleaned the throttle body worked fine for about a year. Replacing spark plugs and wires now, will wait and see before cleaning throttle body. Looking for an answer - how do you lessen a spark plug gap?

Since my last post everything is working fine without having to clean the throttle body.
