jdpiii3 Posted July 30, 2012 Report Share Posted July 30, 2012 Hi guys I’m Joe and new to Silveradoss.com. I’ve owned my SS since 2005 I love the truck. I also have a 2002 Corvette Z06 As of late I have been having an issue with acceleration, if I try to launch the truck from a dead stop It feels like the truck is gasping for air/fuel it also sometimes feels like it might stall out at a traffic light and the RPM’s drop below 500. I’ve cleaned the mass air flow sensor & and the throttle body I also did a full Seafoam treatment. Wires and sparkplugs are 1 year old. I’m not getting any codes and the truck runs fine at speed and accelerates well when moving or passing. Any ideas? Quote Link to comment Share on other sites More sharing options...
silverado777 Posted July 30, 2012 Report Share Posted July 30, 2012 Does it only happen when you try to launch like your are racing? Or just every time you take off from a light? Quote Link to comment Share on other sites More sharing options...
jdpiii3 Posted July 30, 2012 Author Report Share Posted July 30, 2012 only when I launch like I'm racing, if accelerate normally its fine. I will get the same gasp for fuel/air if the truck is in park and accelerate hard Quote Link to comment Share on other sites More sharing options...
silverado777 Posted July 30, 2012 Report Share Posted July 30, 2012 Have you pulled a few of the plugs to see how they look? How does it act when you stomp on the throttle while driving down the road? Quote Link to comment Share on other sites More sharing options...
MARTYW Posted July 30, 2012 Report Share Posted July 30, 2012 No real ideas other than what Steve is saying. Welcome to the site! An SSS and a Z06 is a nice duo! Quote Link to comment Share on other sites More sharing options...

jdpiii3 Posted July 30, 2012 Author Report Share Posted July 30, 2012 I'll pull a couple of the plugs and check them, the are about a year old. The truck has 123,000 miles. I changed the knock sensors a couple months ago and replaced the manifold gaskets but not the throttle body gasket. Could the throttle body or mass air flow sensor be going bad? I have an airaid air system installed Isn't the fuel filter installed on the fuel pump in the tank? Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted July 30, 2012 Report Share Posted July 30, 2012 (edited) Rich bastard That is no way to welcome a newbie. Have you checked the accessory drive for something dragging the motor down? A bad bearing in a water pump, alternator, or tensioner can drag the motor down and cause those symptoms. Is your AC on when this happens?

I never thought to check any of that, I will and yes with the A/C on or off. Maybe time for a new serpentine belt?
