tryong to seafoam my car using the brake booster line and it wont start when i pull it off car is at running tem and everything why would it do that.thanks

 

hold your finger over it so you don't lose so much vacuum....

 

Funnily enough thats exactly what I told him on another forum and someone else replied saying it will only die if you hold your finger over the line, some people, go figure.

 

sorry i posted this right after the other one

 

Thats ok to post on both forums. Some people read this forum that don't read that one. I was merely commenting on the poor thinking of the individual who suggested blocking off your brake booster line would cause the engine to stall, nothings wrong with what you did.
