1988 toyota supra - at 2000 rpm Have replaced air manifold meter and all hoses. Problem started after a hose burst. Car did not overheat. Replaced that hose and went ahead (due to age) replaced all hoses. When driving slowly (such as parking lots), car bucks badly at about 5-10mph/2000 rpm. Did some research and determined it might be the air manifold. Replaced that. Some improvement -bucking was not so prominent, but car cannot maintain steady rpm.
Have taken to four mechanics in the (DC) area, none have been able to figure it out. \ I just want to enjoy the car as I have for almost 24 years.
