Second opinion] I have a 1998 Chevy short wheel base Stepside with a 4.3 V6 . I have lost the power if I give it gas to get up on the interstate backfires sputters acts like it don't want to go then it will smooth out and then whenever I'm cruising at 70 80 it'll start jerking I think it's the fuel pump Maybe I replaced the fuel filter and I also change spark plugs and wires Maybe 5 months ago. I've been told several different things I just recently got my exhaust fixed I had installed at another exhaust shop they put glass packs on and removed one of my O2 sensors and two was left they did a terrible job . So I just had brand new O2 sensors put in the guy told me I needed to get it reprogrammed that might help I also was told that it could be my mass flow sensor I need to get some cleaner clean it give me a new filter or a new sensor I had O'Reilly's hook their computer up to it and said something about fuel pressure they couldn't tell me what because I didn't have a gauge.
