CHECK ENGINE~SURGING CONCERN

Dodge Dakota

Hi~I am recently (2 days) a proud owner of a 2000 Dodge Dakota Quad Cab 4x4 SLT with the 3.9L engine, it has 78,862 miles. My question is this on my way to work the engine light came on.I stopped checked the gas cap it seemed loose so I removed it tightened it and went on my way, how can I reset the light? Secondly, at highway speeds between 60-70 mph the rpms seems to fluctuate, like it is searching for a comfortable spot to be. Possibly because I am not used to driving it yet? However, it also does this slightly at idle as well~any help would be great. Thanks, Wendy

I've got a 2000 4door dodge dakotaV8 4.7 liter. 145,000 miles
My truck's engine speed (RPM) fluctuates at cruise speeds between 50-75mph. It only fluctuates couple hundred RPM's but enough to make me wonder whats wrong, and get on my nerves.
If you ever figure this out, would you let me know?
