Recently, the car has not been running up to par. After driving the car for a few days, the problem became worse and would stall when stopping in traffic. However, the car ran fine at normal driving speed. Also, I have made inspections to the air management and vacuum emission hoses. So far, I cannot locate any leaks.
Car is super clean and hoses are like new.
I am still having the problem of getting the car to idle and after the car reaches normal operating temperature. The code 44 will repeat even after re-setting the computer. I have checked for a short from the ECM connector to the O2 sensor and seems to be in working order. Which I believe rules out the ECM being defective. The TBI units seem to be in balance with each other, both injectors have a very good rounded spray of fuel, and both respond with an increase of the throttle.
