Jeep hesitating and stalls
I have a 99' with 138,xxx on it. When I start it and take off around 30 mph it will bog down and rpms drop if I step on it it works the hesitation out of it. Then when I start it up no matter if its cold or warm same thing. I have already put both o2 sensors in it. I'am kinda leaning towards some sort of fuel problem. I also have a code 1494 for leak detection pump checked all evap lines and changed some rubber boots still coming on do these pumps go bad?
