I am having trouble with my 7th piston in my 1998 Tahoe. I was thinking yesterday on ways to fix the problem because i already get horrible gas mileage and the fact that the fuel injector is still pushing gas into the piston which isn't firing properly can't help the problem i was wondering is it possible to remove that fuel line and put a straight peice of metal in it's place and rtv the piston shut? I thought this because if i replaced the line to the fuel injector i should just be able to bypass the 7th piston completly and save me a little gas. Will this work???
