Hi my 2001 GMC JIMMY is shaking and wobbling and wont let me accelerate over 40 miles sometime,6 months ago I replaced the fuel pump and fuel filter dont know what could be the problem,car ran hot last month so I had the water pump replaced car stop running hot. Now I smell this weird smell when driving smells like some sort of battery or wires burning,when I press the gas peddle I hear a air sound or some sort of wind gushing sound it jerks and shakes and sometimes I hear a rattle, I am scared because this is my only source of transportation dont know what the problem could be please help.
