Fuel Issue

[5150coupe]

using 19lb injectors and maf sensor is calibrated to 19lbs as well. not sure what year the engine is from.

i tested the car again today and unfortunately the ect, or lack of one doesn't seem to be the cause of the issue. next i'm going to check out the egr to make sure it is functioning properly. any other suggestions will be appreciated.

again...now that the issue has been happening for a few weeks now i have noticed that the issue seems to happen just a few minutes after driving down the road while cruising. for about 20 seconds i lose any throttle response, the engine boggs down, and if i give it any throttle the engine makes popping noises. i have to basically wait out this period of time till suddenly the power returns, throttle response is perfect and it seems as though there was never an issue. the issue occurs once when starting out and then seems to go away untill i stop somewhere, turn off the engine, and the car sits for ten or 15 minutes. when the issue occurs i have noticed more than once that i am giving it some gas and the motor isn't responding and then all of the sudden the car goes back to normal.
