My 95 Blazer has been idling rough since I took it on a hunting trip in
South Dakota (1500 miles in 5 days). I cleaned the EGR valve with sea
foam and that did not help. The check engine light comes on every so
often and I did get it to read a cylinder three miss fire. I replaced the
wires and plugs. Check engine light went out but still runs rough. I
decided to replace the fuel injector spider assembly since it was original
equipment (142K). The engine is new last year and has about 20K. I was
thinking of replacing the EGR but there is not engine light (yet) and they
are expensive. I already have about $350 in it and am in need of some
help. Any suggestions.
Did you replace the fuel lines inside the plenum when you replaced the
injector? Cylinder 3 is on the correct side to have a leaking line
cause a misfire. The kit you need is called a "Nut Kit".

Yes i did replace the intake fuel line or the nut kit. It looked like the
fuel line was leaking at the back of the air plenium where it connects to
the fuel lines. I did check the gas milage and it seems like i am getting
an extra two miles per gallon! The thing just runs rough after it warms
Thanks for your reply.
