Default Did seafoam, now high rpm miss??

I did the seafoam to my car when you suck it through the brake booster hose and now it seems to run a little better but at high rpm's it kind of pops and misses. I replaced the opti about 15k ago and new sparkplugs when i put the headers on about 4 months ago. I was thinking maybe o2 sensors got all gummed up from the seafoam but im not sure. Anyone have any ideas?

Did you put new plugs in it after using the Seafoam? If not that is likely your problem.

Why do you say that?

It is very likely it may have fouled the plugs.

It might've trashed your O2 sensors too...

I vote plugs and or o2 sensors. Common when people use it sometimes.

I thought seafoam was supposed to be safe on everything? I'm wanting to do it on this car, but maybe I will just stick with the gas tank and oil treatment.

I hear ya, I've ran seafoam on many different vehicles without any problems. And you will really notice a difference most of the time, but I don't know about putting it in a brake booster line and all that. I've always done a gas-tank treatment and a little bit in the oil... which you would think would knock-out quite a bit of carbon build up. I don't think it's worth going allout on sea-foam if it risks anything.

It doesn't actually damage anything. But the deposits that it burns out of the rest of the engine tend to accumulate on things like spark plugs and sensors. This is especially true on high mileage engines that have never been routinely cleaned out.

It's not bad stuff, but if you go by what it says on the can, it does everything--and would probably have even saved Challenger and Columbia had there been any onboard...

I remember a post made about a guy who put it in the oil of his Honda and threw a bearing. He stated the instruction didnt say exactly how long he should / could leave it in the oil. Now he is suing. Like I said it's not the safest stuff in the world and you need to know what youre doing. If anyone really thinks different thats fine just dont make a post when you screw something up and dont try to sue the company because youre a tard.
