Hey guys looking for some input: This vehicle is on a stock tune, I wanted to get this somewhat running ok before I attempted to tune it.
2001 Silverado 5.3. starts and seems to run fine at idle when I step on the gas it is very sluggish off the line and struggles to go anywhere. It just Boggs and acts like it has no power.
I have checked Fuel pressure and it is steady at 58/59 psi.
Cleaned out the MAF.
New plugs
cleaned the throttle body.
Checked for vacuum leaks.
Was curious if anyone noticed anything out of the ordinary with my VCM log. I am still a newbie, and my experience is limited using the VCM suite.
