Fuel Pump?? Several codes and issues
The MIL came on last week and stayed on until I cleared it, Once the fuel level was down to right under a half tank, the light came on again with the same codes. Filled car up, and cleared light. Light did not come on until it was below half a tank again. When first starting from a stop the car has a hesitation and then will finally go. I have not had any issues with stalling or the engine quitting. MPG has dropped by about 3MPG on the highway.
Has new plugs and was running great up till last week.
Here are the codes i'm able to pull using VCS Lite.
P1136-Fuel Trim: Bank 1 (Add): System too Lean
P1423-Secondary Air Injection System; Bank 1: Insufficient Flow
P1411-Secondary Air Injection System; Bank 2: Insufficient Flow
P0431-Warm Up Catalyst; Bank 2: Efficiency Below Threshold
IM thinking the P1136 may be the pass side fuel pump going bad.
Anyone have any suggestions or comments??
Thanks a million.
