[QUOTE="alantiong, post: 698956, member: 19754"] am with mizhan on this. Oxy Sensors.. been there twice... when oxy sensor is faulty, it senses "rich" and cut fuel level. this is only at partial throttle. at WOT, the system bypasses the AFR, so car will run rich full flat all the time. to test. Just unplug it. the car will run rich. but will smoothen out. then take your time finding good bargain. heheh [COLOR="silver"][SIZE=1]- - - Updated - - -[/SIZE][/COLOR] am with mizhan on this. Oxy Sensors.. been there twice... when oxy sensor is faulty, it senses "rich" and cut fuel level. this is only at partial throttle. at WOT, the system bypasses the AFR, so car will run rich full flat all the time. to test. Just unplug it. the car will run rich. but will smoothen out. then take your time finding good bargain. heheh [/QUOTE]
