Currently, I am using Slick 50 Fuel treatment that I bought at Advanced Auto in the clearance bin for $1.99. My car is experiencing some weird idling behavior. My car idles fine and smooth, however, every 2 minutes or so, the RPM would drop from 800 RPM to 400 RPM for a second then back to normal. A big and brief idle rpm drop like that makes my car go from silky smooth to vibrating death mode. All maintenance were done in accordance with the owner's manual.
Weird idling while using Slick 50 Fuel additive.

Did the manual say add Slick 50?
Might be some deposits being cleaned out? Might be a dose of cleaner that was not mixed up? Or?
$1.99 Slick 50, hmmm. Snake oil at its finest.
I would have used Seafoam or Redline fuel treatment.

Sounds like a vacuum leak.

If you did all the maintenance in accordance to the manual [which I am sure you did as you give your car excellent maintenance] there is no reason whatsoever to use that snake oil.

Is the A/C on cooling mode or the windshield defogger that would run the A/C? How about cyclical high current draw accessories like heated seats? The PCM should control the idle speed when a sudden heavy load hits the engine like the compressor clutch kicking in or a heavy load on the alternator. It seems to me like a vacuum leak would increase the engine speed rather than cut it down, but I don't know what kind of car you have. A carbureted engine could behave differently. I would check the Idle Air Control valve and make sure the throttle body bore and blade are squeaky clean and the IAC is connected. If the IAC valve or the throttle blade is sticking, it could cause the RPM to drop under heavy load because it can't let in more air to make up the difference. You can probably clean both of them, and if they are badly gunked up, you should check the PCV system to make sure it has vacuum and the valve is working properly.
Just a thought anyway. And yes, even at $1.99, the oil additive is not worth it..

I have no reason why people think it's the Slick 50 oil additive when I clearly typed "FUEL TREATMENT".
J.A. Rizzo: The same symptoms show when my cooling fans kick on and I can hear the fans clearly. However, this time, the engine acts if there is a load every 2 minutes and there's nothing to be loaded. I will check the other parts you mentioned. Thank you..

I used their Oil Treatment once, and never considered their stuff again. I stick with regular STP and other brand regular injector cleaners. None of that "special" stuff for me. What I found amusing when racing was racing the teams were sponsored by stuff they could not use IN the race car; Slick 50, The Outlaw, Z Max, etc.
Snake Oil is just a name for a gimmick product!
I am sure we all read that you used the fuel treatment. It is still snake oil though.

Might want to clean your throttle body and MAF if you haven't done so before. I'm also wondering if the cleaner has loosened up anything in your fuel tank, which may have gone into your fuel filter and caused the problem at idle, when it may not be noticeable when driving.

And may I ask how many people cautioned you against using garbage like Slick 50?
