99 ford contour with check eng light flashing sometime's
my car has the 2.5 liter svt motor with 98000 miles. engine code G. the check eng light recently started flashing on me periodically. i took it to my dad who has been a tech for over 34yrs. certified in every field. we spent all day a week back trying to diagnose the prob with a scan tool. it put's out these codes po 302,300,and 306. in mode 6 it puts out a 41-12, 51-07,08,090a and also 52-00. Its showing a misfire on the back 3 cyl. when you pull those plug wires you can hear it drop the cyl. it doesn't do it all the time and it also drive's and shows no sing while driving that it is misfiring or any loss of power. he is leaning towards the computer putting out false codes but not for sure. has anyone else experienced this prob or have any idea's were at a loss. thanks Jason
could be a bad computer,the contour was known for that problem.another thing could be bad 02 sensors,or a cloged cat converter.
