Seafoam

Yes or no? I have 140,000 miles on her? Will it really clean out the bad stuff? Thinking about doing it then changing the oil and the spark plugs all at the same time. She seems a little sluggish these days.

I've done the sea foam with good results. But I also just replaced my factory upstream o2 sensors and that made a big difference.

Yeah, I'm afraid of messing something up too. I've only heard good things, but I'm still a little nervous about it.

I'm thinking that's got a lot to do with the performance right now. I need to go in and change the little maintenance things.

The videos I've watched looks easy. You put some in the gas tank, in the engine and run it through a vacuum line. Check out YouTube.

Well the chemicals eat away at the carbon deposits in the intake and clean fuel lines when added to gas. I've run full bottle in tank as well as done the 1/3 in tank 1/3 in crankcase and 1/3 into the vacuum line. Makes car smoke and sputter so you need to be able to work throttle cable so it won't die on you. Then after it burns off I drove for about 50 miles and got oil change.

My car has 180000 on it and when I put new o2 sensors in it felt like I got some power back. Throttle response was better and the mild gas smell went away. I wasn't throwing any codes I just think the sensors were worn out and reacted slowly to changes in exhaust causing rough idle and bad mpg.

What exhaust are you running? I have a bassani catted xpipe with flowmaster and I have a little stink to it now. I've had the car for about 1 1/2 years and haven't changed anything except the oil. I think I've put about 20,000 miles since I've had it..I figured it's about time to change the plugs so I thought I would do it all at the same time.

You need to make sure if you think you have no cats. Are you showing any check engine light? If you don't have cats then what you have might be mil eliminators.

Well I would think if the car is still using the sensors and the sensors are old like mine were it might not hurt to replace them. I got mine from rockauto for 25 each. Oem Ntk from Japan.

Well make sure your car is cool. Was very tight on right side. It took bending a wrench and a crowbar to get room on the right side.

Did you install the h pipe yourself? I would run some seafoam through it, change the plugs, tranny oil, flush radiator. Just a good clean up.

I say do it, I did it at 154,000. Can't really tell performance wise but I mean its $9.99...it certainly doesn't hurt to do it. Only this is, make sure when your pouring it into a vacuum line that a buddy is on the gas and you pour it very very slow. Every other step is pretty easy.

You only have two o2 sensors because only the two right after the exhaust manifold matter to the computer. The two After cats or downstream ones are for telling the efficiency of the cats, which if you have none they are useless

Well that's true. But opening up the exhaust from factory sizes like piping to 2.5 inch to 3 inch tips. Idk what the stock size is

Seafoam is good stuff. My wife's minivan had a P0303 miss. I put two cans of Seafoam in the gas tank when she had about two gallons of gas in it. Ran it about 30 miles and put two gallons of gas and one can of Seafoam. No more miss, no codes, much better power and acceleration, better idle, and better gas mileage. It worked great for me!!
