Turbo whistle what could it be?

[suprat]

Well right now i try not to run the car at all cause the times that i do run it the car bucks like a bronco and i cant give it to much gas cause it will bog on me. If i slowly ease in to the gas pedal and don't go over 3000rpms the car will run up to 60 miles an hr or more but as soon as i give it to much gas it bogs down on me. Thats with the afm disconnected now with the afm connected i have to keep my foot on the gas to keep the car runing and when i take off the bucks no matter what. It wants to shut off everytime i have the afm connected but when i disconnect it the car will stay runing but very rich you can see the black smoke but again once i connect the afm the smoke goes away but the car will stall. Oh and since i wanted to make sure it was the afm i connected and tape it while the car was runing and right when the car was about to turn off i tape it and the car came back to life as soon as i stop hitting the afm the car stalls out.

By tape, do you mean tap? If you are tapping the afm and it is affecting the way the car runs, it's bad. Plain and simple. You can buy used ones off ebay or at the junk yard, Lexus 1UZ V8's use the same sensor (not the same housing). You may want to consider replacing it with a maf translator and a GM maf sensor. You can probably buy both new for less than a new KVAFM.

hmm might have to try that, for the sake of science.
boy that would be a great prank to play on a buddy.
