[QUOTE="EddieS'04, post: 978277, member: 61136"] JB, The air/fuel ratio is off. Lean would mean the air ratio is higher than it should be. Several varibles. Could be air being pulled in that is not being monitored,by the MAF. Or air is not monitored correctly. Or Starving for enough fuel for proper ratio. 12/1 to 14/1... Could be a bad O2 sensor. There are some other varibles to cause it also. ECM may not be performing properly. [/QUOTE]
