- Sea Foam. It's available at most auto-parts stores and comes in a little red and white can. Warm up the car and take 1/3 can and slowly suck it directly throught the intake manifold via a hose connected to a direct vac. source. I don't understand what your saying here. Are you pouring it over the manifold or are you pouring it into the manifold. Sorry I am not a mechanic. And what are you doing with the vac? Keep the other hand on the throttle and do not let the car stall. As soon as the fluid has been ingested, scoot around to the keys and shut the car down. That's right - turn it off. Let it sit for a good 5 or 10 minutes, then start it up.
Does it make a difference if you don't have a throttle cable. I have a 1990 Alpina B10 and it has some electronic throttle rather than a cable.
Thanks Jesse
