1995 Lexus ES 300 Repair Question
Asked on November 13, 2011
Obd po100, po110. why is the power or fuel supply intermitent. RPM will not exceed 2.5.
This prob. is intermittent. Changed old Battery, the next day the engine light came on i checked the obd and codes po100, po110 came up. symmptoms are afterthe car starts in park 900 rpms usually 1000-1100. put in drive and step on the gas and it bogs right down but rpms level off and does not stall.to get up to 30 mph i have to keep it in low and gradually give it more gas. if i step on the gas normally it bogs right down. Then shift to second then drive rpms never get over 2.5. then after driving 10 miles or so locally the engine light goes off then back on and the car resumes normal working condition. it feels like not enough fuel to engine.

P0100 is the Mass Air Flow Sensor, MAF and P0110 is the Intake Air Temperature sensor, IAT.
I have provided you with the diagnostic code diagnosis and repair for each. I also gave you FIG 6, from the Trouble code and repair sheets which is the ECU Pinout. FIG 1 is just where to connect the OBD tester at the port on the dash.
