The engine has been rock solid and not given me any problem yet.
It's been a good truck, but I wish the cargo area would be a full 4 feet across to load 4 x 8 plywood without having to put them on top of the wheel well.
It's a comfortable ride.
I did find this review very informative.. Thanks :) I just bought my first 1991 Jimmy 4x4. a real good guidline as to what may happen. thankyou!
My 91 Jimmy has been a great little truck. I am going on 200k and have done very minor maintenance. My engine has also been rock solid and still burns no oil whatsoever. GMC really had their stuff together on this one.
My 91 jimmy has had many problems with burning oil only at 100k it is a POS.
My 91 Jimmy s-15 is awesome. It is so durable, I really love my truck! The ignition control module just went out, so I am replaceing that again, after a year. I guess these go through icm's pretty regularly so I got the lifetime warranty. I just put it in and it's not turning over. I'm sure it's something small. My truck has 280,000 miles and still goin' strong. The cosmetic parts definitley can't hold up to the life of these trucks!!
