DRH1998
Newbie
Hey all. I have a 1998 Chevy 5.7 and have had good luck with it up until this point. It sputters under load and idles a little hard sometimes. We have replaced plugs, wires, distributor cap, spider injectors and got to the point last night where we cut the cats off to see if that would make a difference, and it did help a bit but it still sputters under load and only when the truck is warm. There was an O2 sensor code but that’s it. Also is a pig on gas now
Any suggestions on what this could be is appreciated. Also did a compression test and it all came back good. The engine probably has 400k on it
