sea foam engine stall

have a 1993 skylark 2.3 4 cylinder engine poured some sea foam in air cleaner case so it would be sucked thru the throttle body.was told later i should have poured it into power brake vacuum hose, which we did after i got a second can. none the less before i did this the engine ran good with no problems ( stalling out shortly after restarting.
we cleaned out the air cleaner case.
after pouring sea foam thru the vacuum hose and taking the car for a little drive to burn up the clear as instructed I stopped at an auto store to get oil/oil filter air filter ,restarted the car and it stalled after going 10 feet.
it now does this every time you restart the car. but it runs fine after you re-restart the car . the only other thing we did was change the oxygen sensor
any help would bo getaly appreciated as i don't have much money to spend taking it to a repair shop ,just recovering from a heart attack quadruple by pass
