Yes, and its on sale at Oreilly's for $6.99 a can. I run it through my rig when the rough idle starts to come back on my F150. It doesn't do the trick on my Expedition though. I'm still trying to figure that one out.

Thanks for the update. I will definitely look into replacing the COP boots.

What I did do though is change out my spark plug boots that i got for 50 bucks at a Napa store, they were the only ones that had them, and the idle went from completely crappy to steady with a intermittent misfire that I can feel about every two to three seconds. So my advice to you Dx2ry is to change the COP boots out because it will make a world of difference. I think that they just wear out and they don't keep a tight seal on the plug so it allows the wire to move freely not allowing it to have a good connection sometimes. I agree about the second opinion. I really think they are trying to scam me for some money. Through all of this i also had the brakes wear out on my 2009 Honda civic at 21,000 miles. That isn’t very many miles and on top of that the dealer wanted 250 bucks to change the two front brakes out. I told them no and brought it home and did it for 50 bucks. the beauty of it thought was that I got the lifetime warranty ones from AutoZone so i will hopefully never have to pay for new pads again. The moral to the story is that these car dealers are getting more and greedier and I think that I will never take my vehicle to a dealership again. Good luck to you guys and keep me updated on what you find out with yours and I will do the same.ffice
