I recommend checking the EGR valve first as GM cars and trucks of this era are famous for small ckunks of carbon getting lodged in the valve seat and holding the valve open causing rough idle and general undriveability.

    where is the erg valve on 95g20 van

  • John Smothers III Apr 16, 2011

    The throttle body located in the center of the intake manifold hides the EGR valve which is mounted in the intake. First, get a new EGR valve gasket, then remove the two bolts securing the the valve. Remove the valve and invert it, you will see what looks like a pencil sized piston in a barrel about 1/4" in diameter. Prod this piston to see if it has full range of motion while watching inside for little chunks of foriegn material. This can usually be dislodged with a small screwdriver or by air while holding the valve piston open. Clean off old gasket and remount EGR with new gasket (NO ADHESIVE).

95 chevy g20 van started to lose power while driving and began to spit and sputter


Ck your alternator output, should be between 13.8 and 14.2 volts, A bad alt will cause the battery to discharge when driving, Once voltage drops to a certain level (9.8 I think ) the ecm starts to shut down causing all kinds of strange problems, like running bad ,trans not shifting right, even the radio ! It happened to me in my 95 chev p/u

My 1992 chevy g20 van surges and i'm not sure exactly why. I changed the pcv valve, fuel filter, spark plugs, and air filter. What are some possibilities


My first thought would be a vacuum leak in one of the hoses. Rubber hoses get brittle with age and even a small crack in a hose may cause surging. Happened to me in a Lumina.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.
