Box truck sputtering

Asked by Guru5BC82 Jan 09, 2018 at 08:29 PM

Question type: Maintenance & Repair

I have a 1995 Chevy van 30 HD which is the same
as a G30 my truck sputters when I go down the
road especially when I reach speeds above 45 I
have changed the obvious I have given it a tune-
up plugs wires distributor I have replaced the fuel
pump I replaced the TPS sensor I replaced the
fuel pump relay and I replaced the fuel filter I
noticed that I had a ground missing from the
battery to the block so I added that also I had one
vacuum leak which I have sense repaired I have
tested the distributor for spark good there it
seems to me like I'm not getting enough air
possibly? I checked the throttle body I am getting
plenty of gas there I have a feeling that it's going
to be something simple that I'm overlooking but
any ideas would be appreciated because I'm
running out of options

Is the exhaust system clear ??? Cats can decay throwing lumps into the tail pipe or the baffles in the muffler can rust off and restrict the exhaust !!

Whoever owned the truck before I did cut off the catalytic converter and straight piped it but I have not checked the muffler baffles because it mainly does the spudder when I'm going down the Road it almost feels like it's gasping for air and not an overabundance of fuel
