My 2000 s500 with 55k miles (out of warranty) misfires.. That is
when I start driving it cold it runs good unless I step on the gas
hard.. then is stumbles and doesn't accellerate at all.
I took it to the dealer and they hooked it up to the computer which
said it had a misfire in cylinder 4 and 6 and would be about $400 to
Any idea what this means ? or if I could have a normal mechanic fix it
instead of my overcharging dealer?
