So the car has sat for some time. I had the body off of it. Drove the car around w just headers and it runs great. Put everything back together, and drive the car, and it drives like ****. It bucks really hard in first and second gear, and you have to be real gentle with the gas, it it goes violently into a bucking. Which really the only way to stop it is to stop the car and start all over again. Any ideas?
