I have a 1999 maxima (loaded) and last year I had two (one and then
second different one a couple of weeks later) sensors (o2?) replace
after running rough.  Car ran fine then recently had 2 coils replace
at a local garage after check engine light had come on.  Now th
traction control system seems to be acting up - a couple of days ag
the light came on while driving and later went out - It came on agai
yesterday but when i started it this morning it is off now.  I calle
a dealership this morning and they said they'd test it but sound
like I probably need to replace the other 4 coils all together (an
perhaps they said plugs too but I wasnt sure whether that wa
included or an additional option.)  A
Does this sound like the reason the traction control system light cam
on?Does this sound like the solution and is $578 a reasonable cost fo
them to do a 4 coil replacement or is this unreasonable or a simpl
type fixable thing???  Thanks, Dav
