Have had 2 oil changes done; one at the same time as the rest of the tune-up, and one when I first bought the vehicle 2 months ago. Entire fuel system has been cleaned. One dealer, 2 private shops, 4 mechanics who work on their own, along with myself and my dad, who know quite a bit about vehicles, have yet to be able to find what's wrong with it now.
The vehicle is extremely slow for a 4.3L Vortec motor. It has been unreliable in the 2 months I have owned it. There are more things that have gone with it, but just don't even have the room or time to go through everything.
The 4.3L Throttle Body Injection motor is fairly good, but the 4.3L Vortec motor on 1995 and older vehicles have proven to be nothing but trouble.
I have owned multiple types of cars, and General Motors vehicles have proven to be nothing but trouble. I will never own another GM again. I feel GM needs to take some hints from foreign car manufacturers on how to build a vehicle. Unless you want a vehicle that is expensive to buy and more expensive to keep on the road, I would not recommend buying it. I am scared to death of driving it for fear of it leaving me stranded again.
I have owned this vehicle for 2 months, and am already looking to sell it, even though I paid 2000 for it and have $2500 in repairs. It's been in the shop more times than I can count. I have only had one other vehicle as bad as this one. I am done with GM vehicles, and probably wouldn't take one if you were to give it to me.
I do regular maintenance myself, and this vehicle was bought off of an individual who bought it brand new (one owner vehicle), and had full maintenance and repair receipts, and he did take care of it per the manufacturer recommendations. He even had about $5,000 worth of repairs he had done.
GMC, when making this vehicle, decided to make a vehicle to leave people stranded once a month. No wonder why every mechanic I have had it to, including dealers, have said they have a 1991-1995 GMC Jimmy and Chevy Blazer with the 4.3L Vortec motor in at least one a week, if not several. It's definitely a mechanic's favorite vehicle, as they can make a living off of repairing them only!
