I was driving home this evening and I started feeling slight lurches and then more severe lurches. I had been getting a fair amount of rattling upon acceleration the past few days. I have been hearing dieseling over the last few months and my dealership said it was nothing to worry about. Back to what happened. I exited off the highway and just made it back to my store. As I was driving on the city streets everytime I pushed down on the accelerator I was hearing the rattling and getting very little power and constant soft lurching. Anyone have any ideas. I had a head gasket go on a previous car but that was pretty qucik and a complete loss of power. I have had concerns about the timing chains and also the noisy fuel pump, of which the pump is supposed to be replaced this Friday. My warranty did not want to cover the pump unless it completely failed. Does this sound like a totally failing fuel pump, gasket issue or something else. Needless to say I am really pissed at the dealership since I have had nothing but constant issues with this car. Please send me any feedback. Thanks!!
