I've used it in carbs, just drip it in and keep a hand on the throttle to keep it from stalling, but I've never done it in an injected car. I thought I could take off that little crossover pipe near the throttle body, but the car stalls when you take it off. It seems that you would have to spray it in someway. Any suggestions?

 

I would imagine sucking it up through the brake booster vacuum line would work like normal.

 

nope. brake booster only feeds the rear rotor. you need to find a vac line closer to the TB, so the seafoam can be sucked through all intake runners.

check the vacuum system in your haynes manual (you should have one....everyone should).
