President Barack Obama, seeking to end a stand-off between states and the auto industry, plans to issue new national emission limits and mileage requirements for cars and trucks. Obama plans to announce on Tuesday that he will couple pollution reduction from vehicle tailpipes with increased efficiency on the road. It would be the first time that limits on greenhouse gases were linked with federal standards for passenger cars and light trucks. New vehicles would be 30 percent cleaner and more fuel efficient by 2016, according to officials familiar with the administration’s discussions. The officials spoke on condition of anonymity because the formal announcement had not been made.
I just bought a 85 MOnte Carlo and it ran well jus slow on the intial lower miles.. Then after a while it ran nicely.. I replace the spark plugs and now it pops when i hit the throttle and shuts off when i switch into different gears…
if it didnt do this before the wires where changed you probably have crossed a plug wire you will need to check the firing order to make sure they are on the right plug 1-8-4-3-8-5-7-2
