I put sea foam in my gas yesterday and after about 5 minutes of driving the engine got kinda sluggish and loud. It felt like it was running on low octane. Anyone else put sea foam in their L67'* gas tank?

I've used it quite a few times... never a problem here with my L67! In fact the seafoam made it run awesome when I put it in.

It helped mine for the most part. Did you put it directly into a vacuum line, or into the gas tank?

I don't have an L67, but I had the same issue, when I had my old ignition. With the new stuff, fixed the whole issue. No matter where you put it in [except oil {so just tank/vacuum line}], it will make the car sound almost like it'* running very rich, and isn't quite burning it all off, this is a sign of a weak ignition [trust me, I know what a weak ignition is like].

If you put it in the tank, after you finish off the tank, any of the problems you had will be gone. If you put it in a vacuum line, just leave her be overnight, and in the morning all should be well.. if not, after several miles, all of that should be gone.

Are you supposed to wait over night? I didn't, would it have helped if i did?

No, you pour it in, and start up your car.

I recommended the waiting overnight for fantastic, because his engine is slightly flooded with the seafoam, and doesn't have a good A/F mix because of that. Letting the car sit overnight will help clear out the intake of the extra seafoam liquid.

If you experienced stumbling for extended periods of time [IE after the car stops smoking from the tail pipe], then letting the car sit overnight will most likely fix the problem. Otherwise, just drive the car, and it will all smooth out, as soon as all the seafoam is burned off.

When i did the seafoam thing, I put a 1/3 of the bottle into the brake booster line, and the other 2/3s into gas tank just for good measure. I think i still have some of that stuff in my tank. I haven't been driving much this week. Is it harmful to have it in the tank for an extended period of time?

Naw, since you are planning to replace your fuel pump anyways, no worries. SOME fuel system cleaner, if left in the tank for extended periods of time [actually, if the pump is exposed to the fuel system cleaner for extended periods of time, and in our case, the pump is in the tank], the pump will die.. in a few months. Just be careful after you replace your new fuel pump, not to leave things other than gas in the tank for long times. Just cruise for chicks the day you pour it in.. oh yeah, and cruise until you run empty.. that way it'* all gone.

Be sure to check your plugs after this. They could have fouled out causing misfires/rough idle.

Like sugar? Now that'* what we call running rich, or should i say sweet...
