My 95 Blazer is blowing blue smoke out of the exhaust which I know that usually means it's burning oil. But, it basically only does it in first gear. Once the car goes into second it doesn't do it as bad. And it smells like gas. So bad it burns your nose. There is no pick up whatsoever in first gear, and when I'm stopped at a red light or stop sign, the whole car shakes. Could this be a problem with the fuel sensor maybe?

im haveing this same problem with me 95 blazer try haveing your coil checked. Not sure if that will fix it but its been my problem

im not sure so this might be a stupid suggestion but a buddy of mine had a shaking problem and a mechanic told him that it might be the air flow sensor
