1994 GMC C1500 ext cab. 5.7L
I ran out of gas on the way to the station, I put in 1 gal of fresh gas and it started right away but on the way I had to rev it up a bit. 1 mile to the station then I put in 10 gal of gas and STP fuel inj. cleaner, still ran rough and not able to idle. No smoke or excessive fuel.
Next day, Heet water remover, changed fuel filter, and plugs, still runs rough.
I checked EGR last night and it works.
Please help.
