Good morning to you all,

Hope you guys had a great week-end.
I have been dealing with the issue of emission warning light for the past c=
ouple of months now. Whenever I accelerated from a constant speed, for exam=
ple from 60 MPH to 80MPH to pass someone, or when I stomped on the gas peda=
l, the light suddenly came on for a few seconds then went off. At any const=
ant speed, this does not occur at all. I have changed all 5 plugs 6 months =
ago and the car doesn't seem to have an exhaust leak. Any comments/suggesti=
ons?
Many thanks in advance.
John Hosi.
