Hey guys I am 17 years old, I have a 1996 chevy 1500 v6 4.3L, my truck has

been jumping alot when i am at a complete stop.. some sort of oil/gas/water

comes out of the muffler, and it is useing alot of gas too. I have taken it to a

mechanic and he says it is the fuel injectors.. is this true? he charges me

200-250 to install them if I can find them off ebay or somthing, whats a good

place to buy them at? any reccomendations or what i could do??

please help, thank you in advance. - Edgar
