Hi, I am new to the Forum but have been lurking for about 2 years. Very good information here. I just purchased a 2000 GMC Jimmy SLT and am very pleased with the vehicle over all. After about 3 tanks of gas I realized that the mileage is pretty bad and just started noticing a hesitation at a constant speed ~60mph and then it recovers. Immediately thought the torque converter needed help. Took it to a tranny shop and everything checks out. I am wondering if this hesitation could be a fuel delivery problem. I found this thread and am now leaning that way. Is this a known problem 2000's as well or has something changed since the mid 90's models? Any and all input very much appreciated!
