If it's idling too low there's a problem somewhere perhaps the throttle position sensor or maf sensor, a scanner that can read the live data stream can quickly pick it out, Sensors can fail "in range" so they may not set any codes because the computer see's a valid nimber even though it's incorrect. If it has a maf sensor that can be cleaned with brake klenn or carb cleaner you might try it. I hope this helps. Take care.

Probably a little late, but for people in the future, pull down on the plastic cover from the sides, there are two pop in clips holding it there. You'll have to pull the roofing down a bit and you'll see two Phillips screws to release the light, then just change the bulbs. Mine said on the actual bracket that it only used 912 bulbs.

The coils are under the top engine cover(four bolts,10mm) Unplug it and pull it up. Flip it over and there are four small bolts to remove to get access to the coils. Just a note. Most times the coils aren't bad. It is the white cover holding them. It cracks from age and heat, letting the spark threw to the engine.
