Hi Guys I am new to this forum, apologies if I am using the wrong section as I could not find one for Mazda Premacy, figured this is the closest one, anyway here is my on going problem hoping some1 can shine some light to it... It will start OK in the morning then immediatly it will cut out, sometimes it will when you restart it will be ok to drive however when reaches normal operating temp it will cut out again subsequently very tempermental in restarting until the normal op temp lowers. The original ECU was replaced by my mechanic with a original Mazda one (2004), two years later the prob reoccured the mechanic has had it recond but the problem is still there. any suggestion?
