Got a 2002 Saturn SL2. Just changed the plugs and wires and got a noticeable increase in power. Drove out of town this last weekend and got terrible mileage. Averaged around 20 mpg on the highway.
Also noticed that it seemed hard for any passing power on the highway as well.
Idles smooth. Temp shows a tad over 25% on guage. Just did oil change as well. Air filter looks good too.
What could be causing this? What should I check first, second and such? Keep in mind that I am an IT guy and not a mechanic with your answers please.
have the same problem?
