missing at idle
my cas started missing bad one night while i was driving. i took it home and i put in some seafoam to see if it would run better, well it did not help so i started to se what my problem was, well i used my friends auto tap to see what was happening. well my front two o2's were reading 10Mv. so i had then replaced, while i was doing that i also replaced the spark plugs. the car seemed to run better, then it started to do it again, i replaced the wires and at idel it runs rough, but when i drive it, ithe power is all back. it only misses at idle. what is going on, i still have a 1/4 tank of gas with sea foam in it. Would the sea foam be causing my Missing at idle
