I'm getting the 'Service Engine Soon' light on my dash regularly...I only use the car for long trips to Florida 3 or 4 times a year...For these trips the engine runs at 2000 to 2200 rpms for 10 to 11 hours...There's usually one fuel stop and a couple of personal pit stops along the way...The light would come on itermitently...On the most recent trip it was on for just about the entire trip...750 miles down and 750 miles back...The EGR valve and the O2 sensor were recently replaced (just before the last trip)...The catalytic converter was replaced about 4000 miles ago...the current mileage is within 200 miles of 150K...I try to use no-ethanol fuel when I can find it...Any light you could shed on the subject would be appreciated...TIA...Jeffyg
