I have fixed the smoking problem on my 85 gslse. It was the cats, it still smokes a little bit but that is from the atf trick. But now I have a power problem. it revs up fine with no hesitation with the clutch in, but when i put a load on the car it is a dog. I can barely get up to 60 mph, and all the way there it studders. Any one have a idea of what it could be? thanks
