I have a 1998 Z71 4X4 with a 5.7, I had a low power rough running condition and was told it was the catylitic converters. I had both converters, 02 sensors, plug wires, plugs and fuel filter changed. when I
got the truck back it runs good except now it has like a hickup in it. It will do it about 2 to three times within a mile. Took it back to the place I had the repairs done and they cann't figure it out. Any suggestions on what the problem may be.
Thanks,
Gene
