I have a 93 suburban c1500 with a 5.7l. So about a month ago my exhaust broke. Started running really rough. So then i welded it back up. Then just last week it started runnin roufg again. It seems like its not gettin gas or like it has a clogged catalytic converter. I cut the cat off, changed plugs, wires, cap, rotor, and fuel filter. It runs fine for sbout the first five minutes until it warms up. Then it runs really crappy. If i hit the gas pedal it starts back firing and doesnt really wanna go. The only way itll go is if i floor it. Then all the sudden it cathces and off she goes.
Kinda at a loss, if anyone has any suggestins id appreciate it,Thanks ahead of tme. david
