i have a 95 blazer 4.3 vortect with gas coming out of the tail pipe what would cause this any help would be grate thx bobby

 

come on some one must know what will cause this plz help me

 

do you have any codes? 1 your spark plug might not be working 2 the cyl maybe is getting to much gas 3 you might have a stickey valve

 

ther is no cel and i was told this by a grage that i took it too to get it inspeted and ther is gas coming out the tailepipe it is also all black junk in the end im stumped i did plugs and wires and cap rotor all test out ok with spark plug tester

 

how is your rpm your idel does your moter shake when u give gas does it bog down any loss in hp?

 

all of that im at a loss could it be head gasket ? and ty 4 trying to help me out

 

no its not ur head gasket are u really sure its gas and not water that smells like gas?

 

I would wonder the same as above? You would think water would smell like gas coming out of the exhaust. Or maybe you have a cylinder not firing.

 

it is gas 4 sure u can catch it in a cup and burn it i did plugs wires cap rotor and no change yet

 

well you can remove your both valve covers and start up your truck and let it idle then go see if all your valves are moving if it is then i really dont know what it can be. if you still having gas come out then just google your problem....
