1998 Z71 w/ 5.7 vortec running rough
This is no high performance engine or anything,just trying to get it to run.Posted on other forums and no response. motor started to run rough. Would almost die when coming to a stop.Got worse , now it starts runs real rough and when you put it in gear it dies. Fuel pressure at 60 .changed fuel filter,plugs,and distributor cap. I took the injection system out and noticed 2 cylider ports were clean compared to the others all carboned up.Any response would help. Thanks

Battery went dead before i could have someone run the code,so no codes would show. He looked at it last nite and said that 4 and 7 injector tubes were leaking fuel. Thats why those two and around that area were clean compared to the others.So now i guess i going to change those two injectors.Put back together and then see if any codes pop up. Thanks again for the response, seems that other forums either dont know ,or they dont respond very often. Thanks again. If anything else i might need to check ,please let me know.
