Hey guys..
I have an accord v6 with approx 107,xxx on the clock. Ive been noticing it sucking alot of gas...for being a honda. What is the normal RMPs going 70 mph? Im at 3k. Other v-6's Ive driven go to about 2350 to 2.5k at 70. Am i not firing on all cylinders? The air filter isnt obstructed,tho its due for a change soon. The front 3 wires have a red looking residue on them(oil?) And the front 3 plugs have a minute ammount of oil on them, along with a black ring around the white port of the plug under where the wire makes connection. Most all of them have some black on the part that sparks.Not TOTALLY black, but black on the outsides and still a little white on the center. Could this be the cause of high rpms(if they indeed are high)?
Also, in a related, or unrelated sign, on cold days upon starting my vehicle, there is a knocking from the engine. Common, or no? After it runs, it dissappears.
Thanks so much for reading, and (hopefully :P) commenting.
