I have a 1992 3 door 5 speed 1.5L that has a hesitation or dead spot when taking off. For a long time this has been happening and a good friend said it could be the throttle position sensor. If this may be true, where is it? and is it hard to replace? I have found two sensors where the accelerator cable goes. There is a sensor on top of this valve, and there is one on the back. Any help is much appreciated. Thanks, Tony.
