Hi,

I have a 94 Blazer Tahoe LT that my father-in-law gave it to me, he told me that all it need is a oil change and a tune-up. So I did
a oil change and I change the spark plug, spark plug wires, distributor cap and rotor, pcv valve and air filter. I start the engine and
it was hesitating a little, then I drove the Blazer and I step on the accelerator and I saw a black smoke for like one minute and after
the smoke was gone and the hesitation, the Blazer was runing nice with a lot of power for 15 minutes the it start to hesitate and it
woudn't stay on. If I stop the engine will stop and it won't start unless I keep the accelerator all the way down and if I keep the
engine above 1500 RPM is fine event when I'm driving but it woudn't stay idleing and a gas smell.

Please, Luis

1st try changing the fuel filter(usually by the frame on the drives side, around the door). if that doesnt work check to see if your fuel pump is working.
