So I did the maf conversion a little while back. When i first did it the car ran sort of crapy. Stalling surging and a real bad hesitation. Had a buddy adjust the tps and idle/set screw. It was better, but not great. The stalling is gone but the surging is not. Since i had it "in" for the winter i did not drive it that much. Now i want to and the surging is driving me nuts. I read a lot of the other forums and so I spent all day cleaning the TB and Idle Air Control Valve and also the egr vavle. It did not seem to make that much of a difference. I then remembered that with the directions for the MAF conversion it said to disconnect one of the hoses from that vaccum block or whatever on the drivers side of the car. It was the second hose from the left. I had done this earlier and it did not seem to make a difference. I then tried blocking it and the surging seemed to go away. But during driving it seemed like it was starving for fuel or air. I left the port open and it ran like it did before, with a hesitation. I then remember someone telling me that if you disconnect the Coolant temp switch (the one for the computer) it will make the computer think the car is cold all the time, therefore giving it more fuel. Anyway I disconected it and the car feels like it gained about 25hp. Thats not real acurate but it ran a heck of a lot better and was much snapper and faster. Should i keep it disconected? Why is it running like this? Why do I keep typing? Can anyone help?
