[QUOTE="mustangvsix, post: 10806576, member: 74332"] Ok newish symptoms but took care of most of the codes from last time. Symptoms: Fuel Pressure tested when car was on and warm at 49-50psi, would drop when you blip the throttle. Car struggles big time at low rpms (from Idle to 2200rpms). Feels like it wants to just die. Above 2200rpms runs strong, pulls good, feels normal I would say. Doesn't matter if the motor is warm or hot, it follows these conditions. 2 codes: P1152 and P0136. 1152: lack of O2 switches - bank 2 sensor 1 ECM detected sensor at rich limit. Probable cause: Fuel pressure high EGR Stuck open Engine Mechanical condition 0136: Circuit condition Bank 1 sensor 2 power train control module use the o2 to calculate air/fule ration in exhaust O2 defective Fuel system rich or lean - check other codes first Engine misfire condition - repair Fuel pressure very high or low fuel pump or pressure regulator Things I have checked/done: Cleaned IAC Cleaned EGR Replaced EGR Vacuum Solenoid and Vacuum Pressure Sensor Replaced #8 Fuse Cleaned MAF Checked Spark Plugs ensured COP's were seated well [/QUOTE]
