I know that the "fuel service" we do at work also makes a smoke screen just like seafoam. It happens at the dealer also but you just dont see it before they give it to you. Most dealers will pull the o2s before hand but some will leave them in and do it.

I've had issues with seafoam loostening up deposits that were holding things together (ie gaskets) but if you use in the correct doage (1/2 can in gas, 1/4-1/8 can in pcv, 1/4 can in oil prior to change) it should never foul cats or o2 sensors

Sorry, I am a newb
you can buy it at advance auto, autozone, napa, etc.
I have used it in my cars every year or so, or when I notice problems. There's insturctions on the can I think but see what I mentioned in the post above

Or you can do it the safer way and take it to have it serviced like the guy at the top of the page was talking about.

I am not mechanically inclined so DIY is out of the question for me.
If you can plug in a lamp and have mastered "left loosey, righty tighty" you can change your own plugs. It may take a couple hours the first time, but it really doesn't require any special knowledge or any tools beyond basic hand tools.

You need a basic socket set, simple bar style torque wrench, spark plug socket, spark plug gapper, a 4" extension, a 6" extension, a wobble joint, and a long extension, 10", 12" whatever. A stubby 10mm wrench will also make life easier.

Pull the spark plug boot off by hand. Put the spark plug socket on the short extension (either 4 or 6, depending on how much room at that cylinder) and turn left until the plug comes out. Gapping a plug is as simple as bending the little wire until the correct size feeler goes into the gap. Gap the plug, put it in the hole, turn until it feels tight, then put the torque wrench on it and push until the little needle points to the 14 on the ft/lb side. Use the 10 mm wrench and 10mm socket, remove the coil pack next to the spark plug boot, (2 bolts, one top and one bottom) lift it up, do the same thing under there to remove and replace the spark plug. Put the plug boot and coil pack back on, move to next cylinder.

The only remotely challenging thing is getting to the front 2 cylinders on the driver's side, and that's where the really short extension and wobble joint come in. Drop the short extension and socket in the hole, plug in the wobble and a long extension, and you're turning the wrench way above the tight mess.

You'll save yourself almost $300 and it really is that simple.

I've been trying to tell people this in so many threads. You are so welcome.

My uncle always said never to put stuff in the gas tank. I think that stuff is best for older cars with carburetors.

Which really isn't much different than using an additive yourself

just make sure you have the throttle body cleaned very important. jiffy lube doesnt touch it but very easy to DIY but maybe other places like firestone clean it for you as part of their service. Thanx again 2 for 3!

Problem solved. It was short on transmission fluid, about a quart to be exact and told torque coverter might of been sticking, but added the atf+4 and its back to normal, but runs smoother than before w the fuel system cleaning, it needed it but the reason for it dying was the trans being so low.... nuts, just glad its okay now, i love my jeep.
