i have a 1993 surburban, that no one can fix. please help !!!!!!!!
Approx. 6 mos. ago my truck began shutting off at stop lights and such, it would start again only to repeat this action each time the rpm drops below 1. the problem has progessively gotten worse, to the point that to drive you must keep you foot on the gas and brake petal at the same time to keep the RPM above one. After visits with two different mechanics who found nothing wrong I chose to replace the fuel filter and fuel pump hoping that this would solve my problem. Having no success I than sought out the dealership after three months of my truck living at the dealership I had a new computer and throttle body yet the problem remains, and now after all of this the transmission will not change out of first, this is where i need help, What should i try next? Does anyone know if there is some type of fuse, switch or regulatoer governing the RPM, if so where is it located? Also any ideas besides replacing the transmission would be greatly appreciated. All advice pertaining to other aspects the problem would be greatly appreciated as well.
Thanks,
Terrie
