2006 Suburban 5.3 surges and stalls.
Hello,
I have a 2006 Chevy Suburban Z71 5.3 non flex. I started experiencing a periodic hard start a few months back. After awhile it started to stall periodically and surge. I thought it may be the fuel pump so I replaced it and it did not solve the problem. It doesn't seem to hard start like it used to but it will surge and stall at slow speeds. It doesn't do it at first but will once the engine warms up. If it stalls completely it will then hard start. I checked the fuel pressure and it reads fine. It shows no check engine light and I have had the codes checked and its not tripping any. I have cleaned the MAF and the throttle body and noticed no difference. Can anyone help me with this? Thanks
